4 + 4 = 8
Triangle ABC and triangle DEC are
Similar
Not similar
The triangle ABC are not similar because angle E is not equal to angle B
What are similar triangles?Similar triangles have the same corresponding angle measures and proportional side lengths.
This means that similar triangles have corresponding equal angles.
And also the ratio of the corresponding sides of Similar triangles are equal.
Since angle ACB = angle DCE
angle B = 180-( 38+94)
= 180- 132
= 48°
angle D = 180-( 94+15)
= 180-109
= 71°
Therefore;
angle A is not equal to angle D and angle B is not equal to angle E, We can therefore say that triangles ABC is not similar to triangle DEC

A. 35 cm2
B. 42 cm2
C. 12 cm2
D. 24 cm2
Answer:
35 cm²
Step-by-step explanation:
This is because the formula of the area of a parallelogram is;
area = (base) x (height)
since the base is 5, and the height is 7;
area = (5) x (7)
area = 35

Corrected question :
Solve the equation. Write your answer as an integer or simplified fraction.
8n - 7 (n - 2) = 18Required Solution :
The given equation,
8n - 7 (n - 2) = 18★ Multiplying -7 into (n - 2),
>> 8n - 7 × (n - 2) = 18
>> 8n - 7n + 14 = 18
★ On substracting 7n from 8n we gets,
>> n + 14 = 18
★ Now transposing 14 which is in L.H.S. into R.H.S. (Remember that sign would be . So 14 would be -14),
>> n = 18 - 14
>> n = 14

Tamara needs $624 for her budget every week. She works 40 hours a week.
What is the minimum amount Tamara needs to earn per hour?
Answer:
$15.6
Step-by-step explanation:
Based on the given information, it is $15.6. However, it never specified how many hours she works a day and how many days of the week she works, so we must assume it is just 624/40.
Answer:
minimum amount Tamara needs to earn per hour = 15.6.

Answer:
B. seconds
Step-by-step explanation:
We have d=rt
means that t= [tex]\frac{d}{r}[/tex]
Given the units of each:
d: feet
r: feet/second

#QU

[tex]\\ \rm\Rrightarrow \dfrac{UQ}{12}=\dfrac{45}{18}=\dfrac{5}{2}[/tex]
[tex]\\ \rm\Rrightarrow UQ=30[/tex]
Answer:
RS = 30, QR = 12, QU = 30
Step-by-step explanation:
Step 1: Determine RS
We can see that RS on the left shape corresponds to FG on the right shape that is also larger. We can use other sides to help us determine the ratio which will then give us the length of RS. We can also see that the shape has been flipped so EF would match to ST.
[tex]RS/ST = FG/EF[/tex]
[tex]RS/12 = 45/18[/tex]
[tex]RS * 18 = 12 * 45[/tex]
[tex]\frac{18*RS}{18} = 540 / 18[/tex]
[tex]RS = 30[/tex]
Step 2: Determine QR
We can see that QR on the left shape corresponds to HG on the right shape that is also larger. We can use other sides to help us determine the ratio which will then give us the length of QR. We can also see that the shape has been flipped so EF would match to ST.
[tex]QR/ST = HG/EF[/tex]
[tex]QR/12 = 18/18[/tex]
[tex]QR * 18 = 12 * 18[/tex]
[tex]\frac{18 * QR}{18} = 216 / 18[/tex]
[tex]QR = 12[/tex]
Step 3: Determine QU
We can see that QR on the left shape corresponds to DH on the right shape that is also larger. We can use other sides to help us determine the ratio which will then give us the length of QU. We can also see that the shape has been flipped so EF would match to ST.
[tex]QU/ST = DH/EF[/tex]
[tex]QU/12 = 45/18[/tex]
[tex]QU * 18 = 12 * 45[/tex]
[tex]\frac{18*QU}{18} = 540/18[/tex]
[tex]QU = 30[/tex]
Answer: RS = 30, QR = 12, QU = 30

For which shape is 180 degrees the smallest angle of rotational symmetry?
The shape with a rotational symmetry would remain the same when rotated
The shape with the smallest angle of rotational symmetry of 180 degrees is shape D
How to determine the shape?To do this, we simply examine each of the options
Shape A: Cross
The shape has 4 equal sides.
So, the smallest angle of rotational symmetry is:
Angle = 360/4
Angle = 90
The smallest angle of rotational symmetry is 90 degrees
Shape B: Star
The shape has 5 vertices.
So, the smallest angle of rotational symmetry is:
Angle = 360/5
Angle = 72
The smallest angle of rotational symmetry is 72 degrees
Shape C: Composite figure
This shape has a square and a triangle merged together at two ends
This means that the smallest angle of rotational symmetry is a complete rotation of 360 degrees
Shape D: Circle
The circle is divided into two equal segments.
The angle on the straight line of each segment is:
Angle = 360/2
Angle = 180
The smallest angle of rotational symmetry is 180 degrees
Hence, the shape with the smallest angle of rotational symmetry of 180 degrees is shape D
