Question

HELP ME PLEASE

Find the Missing Angle
Instructions: Find the measure of the indicated angle.

Answer 1

Lets name the Triangle ABC

where angle a = 70 degrees

And AB=AC GIVEN IN FIGURE

SO, if sides are equal then the angles opposite to them will be equal too

therefore angle b = angle c = x degrees

Now using angle sum property

A+B+C=180

70+x+x=180

70+2x=180

2x=110

x=55 Degrees
