Don't understand how to find this answer. Can't find my notes for it.

Answer 1

Given that

The two sides of the triangle are 6x and 3x+9 and the two angles are 65 degrees each.

Explanation -

According to the property of the triangle " If the two angles of the triangle are equal then the sides opposite to them will be equal."

Then, we have

AB = BC -------------because angle A = angle B = 65

Substituting their values

6x = 3x + 9

6x - 3x = 9

3x = 9

x = 9/3 = 3

x = 3

So side AB will be,

AB = 6(3) = 18 units.

So opption D is correct.

Hence the final answer is 18.
