Please help me ill give you all my points

x= 95°

every triangle equals 180 so you add 115+20 to gef 135. then 180-135 to get 85. since x is on a straight line with the 85° angle it'll equal 95° because every line equals 180°

The value of x is 135°.

Step-by-step explanation:

First, you have to find the other angle of the smaller triangle. Given that total angles in a triangle is 180° so you have to subtract :

180 - 20 - 115 = 45°

A straight line is 180° so you have to subtract the angle from 180° to find the value of x :

x = 180 - 45

x = 135°

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
