Question

What is the value of v?

Answer 1

39°

Explanation:

Information we need to know

• The triangle is a SAS triangle
• Two of the angles are equal
• Angles in a triangle add up to 180°

As we know, one of the angles in this triangle is 39° this means that the angle opposite it would also be 39°! This is because as the triangle is SAS v and the given 39 has to be equal

Have a lovely day :)

Answer 2

39°

Explanation:

Triangle HJI is an isosceles triangle.

In isosceles triangles the base angles are congruent which means their measures are equal.

So the measure of m∠HIJ = 39°
