10.) The measure of angle 1 is 131° according to the Alternate Interior Angles Theorem. The measure of angle 2 is 49° because 180° - 131° = 49°. I can do this because of the Linear Pair Postulate.
11.) The measure of angle 1 is 65° according to the Vertical Angles Theorem. The measure of angle 2 is 65° according to the Corresponding Angles Theorem.
Hope this helps!
True, it has a 90 degree angle. It’s clear as day. And the Pythagorean theorem works perfectly fine with the two legs and hypotenuse
Answer:
I think your answer is 85. The 50 degree angle on the left side of E is equal to the angle to the right of E. Since both triangles have equivalent angle measurements, D and B are correspondent of one another. Add the 50 degrees to the 45 degrees to get 95. Since triangles total measurements equal 180, subtract 95 from 180 to get 85. Angle D = 85, and since Angle B is correspondent, Angle B = 85°
