Since all triangle's angle's values add up 180 degrees, this means we have to make sure to angles add up to 180.

A. 75 + 35 = 110. 180 - 110 = 70 degrees.

B. This triangle is isosceles meaning 2 of its sides is the same length. In this case, the two sides add up to 140 (meaning they are both 70 degrees). 180 - 140 = 40 degrees.

C. I sadly don't know how to solve it.

D. This is another isosceles triangle. 180 - 36 = 144.

Angle Bisector Theorem

An angle bisector of a triangle would cut the opposite side into two segments that are proportional to the other two sides of the triangle.

Thus,

$\frac{x}{15}=\:\frac{12}{20}$

Cross Multiply the expression

$\:20\times x=12\times 15$

Divide both sides by 20

$\frac{20x }{20}=\frac{180}{20}$

$x=9$

Therefore, the value of x = 9
