+98 1. First let's find the missing angle of the triangle on the right which has the measurements 100° and 30°.
180°-(100°+30°)=180°-130°=50°.
(The opposite side of the 50° angle will also equal 50°)
2. Now we know the triangle on the left has the angle measurements of 50° and 50°. Let's find the missing angle.
180°-(50°+50°)=180°-100°=80°.
3. Since there's a straight 180° line on the bottom, and we know that one measurement is 80°, while the other measurement is 35°, we have to subtract 80°+35° from 180° to find the value of x. 180°-(80°+35°)=180°-115°=65°.
Answer: x=65°
