Answer :
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.
Step-by-step explanation:
Answer:
b) 6
Step-by-step 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
