The sum of two numbers is 70, and their difference 30. Find the two numbers using the process of substitution. Let the first umber = x and the second number = y.
Answers
Answer:
x = 50, y = 20.
Step-by-step explanation:
x + y = 70
x - y = 30
From the second equation x = 30 + y, so substituting this in the first equation:
30 + y + y = 70
2y = 70 - 30 = 40
y = 20
and x - 20 = 30
so x = 50.
Answer:
20 , 50
Step-by-step explanation:
The sum of two numbers is 70 ⇒ x + y = 70 -------------(I)
x = 70 - y
Their difference 30 ⇒ x - y = 30 ----------(II)
Substitute x = 70 - y in equation (II)
70 - y - y = 30
Combine like terms
70 - 2y = 30
-2y = 30 - 70
-2y = -40
Divide both sides by (-2)
y = -40/-2
x = 20
Substitute the value of x in (I)
20 + y = 70
y = 70 - 20
y = 50

(b) What additional information is needed to prove the triangles are congruent by the HL Theorem? Explain.
Answers
Answer:
A)
The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
B)
H-L (Hypotenuse-Leg) Congruence Theorem. If the hypotenuse and leg in one right triangle are congruent to the hypotenuse and leg in another right triangle, then the two triangles are congruent.

A = 4C
B = A+3
=> 4C+4C+3+C = 30
9C + 3 = 30
9C = 30-3
9C = 27
C = 3

∠2≅∠4, m∠2=110°. Find the measures of angles 1, 3, and 4 and explain how you know.
Answers
∠2 ≅ ∠4 = 110° [exterior alternate angles are equal]
∠1 = 180° - 110° = 70° [since angles on a line have a sum of 180°]
∠1 = ∠3 = 70° [since vertically opposite angles are equal]

negative coterminal angle:
Answers
Answer:
0° and 90°, it's Ql. If between 90° and 1800 QQ. ... Find a positive and a negative conterminal angle for the given angle.
Step-by-step explanation:
The positive and negative coterminal angles to -32° are:
Positive coterminal angle = 688°
Negative coterminal angle = -392°
What is a coterminal angle?Coterminal angles are those whose terminal sides and beginning sides coincide.
The given angle measure is -32°.
The positive coterminal angle is:
-32° + 360°
= 328°
Since the angle is not between 500° and 1000°, add 360° one more times:
328° + 360°
= 688°
The negative co-terminal angle is:
-32° - 360°
= -392°
Hence, the positive and negative coterminal angles to -32° are:
Positive coterminal angle = 688°
Negative coterminal angle = -392°
