The vertex angle of an isosceles triangle measures 42°. A base angle in the triangle has a measure given by (2x + 3)°. What is t
Vsevolod [243]

<u>Part a) </u>

we know that

An isosceles triangle has two base angles that are congruent

The sum of two base angles plus the vertex angle is equal to 180 degrees

so

In this problem

vertex\ angle=42\°

base\ angle=(2x+3)\°

42\°+2*(2x+3)\°=180\°

Solve for x

42+4x+6=180

4x=180-48

x=132/4

x=33\°

therefore

<u>the answer part a) is</u>

the value of x is 33\°

<u>Part b)</u> What is the measure of each base angle?

we know that

base\ angle=(2x+3)\°

we have that

x=33\°

substitute the value of x in the equation

base\ angle=(2*33+3)\°

base\ angle=69\°

therefore

<u>the answer part b) is </u>

the measure of each base angle is 69\°
