Answer:
x = 12
Step-by-step explanation:
3(x - 1) - 2x = 9 remove the brackets using the distributive property
3x - 3 - 2x = 9 Collect 3x and -2x (Collect like terms)
3x - 2x - 3 = 9 Use the reverse of the distributive property to get x
x(3 - 2) - 3 = 9 Do what is inside the brackets
x - 3 = 9 Add 3 to both sides (additive inverse)
x - 3 + 3 = 9+3 Combine like terms on the left
x = 12

I found the image that should have accompanied this problem.
The triangle inside the circle is an isosceles triangle. It has 2 equal sides and 2 equal angles.
Angle A = 70° , Angle C is also 70°. This leaves angle R having 40°.
The arc opposite angle R is twice the measure of its angle.
Angle R = 40°
Arc AC = 40° x 2 = 80°
The measure of arc AC is 80°.
Answer:
70° and 20°
let the other 2 angles be 7x and 2x
90+7x+2x=180
9x=180-90
x=90/9
x=10
7x=7x10
70
2x=2×10
