We need the 3 triangles “given” in order to answer the problem
<u>Answer:</u>
<em>0.26</em>
<u>Step-by-step explanation:</u>
<em>This is a Isosceles triangle so every side is 60</em>
<em>equation= 60x+60+60x=92</em>
<em>60x+60x=120x</em>
<em>120x+60=92</em>
<em>60-60=0</em>
<em>92-60=32</em>
<em>120x=32</em>
<em>32/120=0.26</em>
Step 1: All angles in a triangle must add up to 180! Therefore, in the upper triangle, add up the two you know 85+35=120 so the missing angle is 60.
Step 2: Bottom triangle. Your new angle above (60) is the pair of the opposite angle - so it too is 60. So now you know 2 of the 3 angles: 60+64=124 Subtract that from 180 and you get 56...which is the answer for ?
