The vertex angle of an isosceles triangle measures 42°. a base angle in the triangle has a measure given by
(2x + 3)". what is the value of x? what is the measure of each base angle?

the value of x=33

the measure of each base angle = 42 ,69,69

Step-by-step explanation:

Bases od isosceles triangles are congruent,so

2(2x+3)=4x+6 (This is the sum ob both anlgles base)

All angles in a triangle add to 180

4x+6 + 42 = 180

4x = 132

x=33

2(33)+3= 69

69+69+42 = 180

x = 33

Each base angle measures 69°.
