8. (3x-5) mZS = 0 MZR = Р T con A (117 Bux+5)* S
Answers
Answer:
95°, 110°
Step-by-step explanation:
Since we're dealing with a cyclic quadrilateral ,
m<T + m<R 180°
7y + 11y = 180°
18y = 180°
y = 10°
Also,
m<S + m<U = 180°
3x+5+3x-5= 180°
6x = 180°
x = 30°
m<S = 3x+5 = 3(30)+5
= 95°
m<R = 11y = 11(10)
= 110°
Given -
m∠R = (11y)°m∠S = (3x + 5)°m∠T = (7y)°m∠U = (3x - 5)°To find -
m∠Rm∠S(nullifying x and y)
Explanation -
As we know this is a cyclic quadrilateral and it's either pair of the opposite angles sum up to 180°.
Therefore,
m∠S + m∠U = 180° ---(1)
m∠R + m∠T = 180° ---(2)
Solution -
Substituting the values of the measure of angles in (1)
➜ m∠S + m∠U = 180°
➜ (3x + 5)° + (3x - 5)° = 180°
➜ 6x = 180°
➜ x = 180/6
➜ x = 30
Therefore, m∠S = (3x + 5)° = {3(30)+5}° = (90+5)°
m∠S = 95°
Substituting the values of the measure of angles in (2)
➜ m∠R + m∠T = 180°
➜ (11y)° + (7y)° = 180°
➜ 18y = 180°
➜ y = 180/18
➜ y = 10
Therefore, m∠R = (11y)° = (11×10)° = 110°

Step-by-step explanation:
They are all solved kind of the same way. If the vertex of the angle is outside of the circle, subtract the intercepted arcs and divide by 2
for 15) one arc is marked but you can figure out the other arc because there are 360 degrees in a circle 360 - 102 = 258. So the two arcs are 102 degrees and 258 degrees.
some of the problems you can set up the equation and solve.
17) 63 = {(360-x) - x} /2 multiply by 2
126 = {(360-x) - x} combine like terms
126 = 360 - 2x subtract 360
-234 = -2x divide by -2
117 = x
? = 117 degrees

A shopkeeper bought 30 pens for 150 and sold 20 of them for 140. Find his profit or loss percentage
Answers
Answer:
Because the cost price of 30 pens = Rs. 150
So, the cost price of 1 pen = 150/30 =5
so, the cost price of 20 pens =
Rs. 5 x 20 = 100
Cp is Rs. 100
Sp is Rs. 140
So, profit = 140-100 = Rs. 40
Profit % = (Profit x 100)xCp
=(40 x 100)/100
= 4000/100
= 40% profit

Dennis drew the line of best fit on the scatter plot shown below:

y = −15x + 2/3
y = -2/3 x + 15
y = −15x + 3/2
y = -3/2 x + 15
Answers
Answer:
4th option
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 12) and (x₂, y₂ ) = (6, 6) ← 2 points on the line
m = [tex]\frac{6-12}{6-2}[/tex] = [tex]\frac{-6}{4}[/tex] = - [tex]\frac{3}{2}[/tex]
the line crosses the y- axis at (0, 15 ) ⇒ c = 15
y = - [tex]\frac{3}{2}[/tex] x + 15 ← approximate equation of line of best fit

11. Write down three different whole numbers so that: • the median of the three numbers is 13, the range of the three numbers is 5.
Answers
Step-by-step explanation:
Let the numbers be a, b, c in ascending order.
Mean is 7, i.e. (a+b+c)/3 = 7 or a+b+c=21
Median(middle number) is 5, i.e. b=5
Range is 8, i.e. c-a=8 or c=8+a
Solving the above three equations simultaneously, we have
a+5+8+a=21
a=4, hence c=12
Therefore the three numbers are 4, 5 and 12
