Q:
# HELPPP!!!! 10 PTS!!Find the missing information x = _____ m angle A = ____

Accepted Solution

A:

The triangle is isosceles, so the bottom angles have the same measure. So, the angles measure 2x, 3x+5 and 3x+5.The sum of the interior angles of a triangle is 180, so we have[tex]2x+(3x+5)+(3x+5)=8x+10=180 \iff 8x=170 \iff x=\dfrac{170}{8}=\dfrac{85}{4}[/tex]So, angle A measures[tex]3\left(\dfrac{85}{4}\right)+5 = \dfrac{275}{4}[/tex]
