Question

a) 18

b) 6

Answer: the answer to this question is A because the angle is acute angle and when you solve (5x-3) it equals up to 18 when you finish figureing it out.

Explanation:

Answer 2

b) 6

Explanation:

Since this is an isosceles triangle, the two sides are equal and the two angles are equal.

That means

5x-3 = 2x+15

Subtract 2x from each side.

5x-2x-3 = 2x-2x+15

3x-3 = 15

Add 3 to each side.

3x-3+3 = 15+3

3x =18

Divide each side by 3

3x/3 = 18/3

x =6
