Remote interior angles are the two angles that are not supplementary with the exterior angle of a triangle.
<c and <a are the remote interior angles of <y
<a and <b are the remote interior angles of <d
In a tight triangle, one angle measures 90°. All triangles add up to 180° according to the Triangle Sum Theorem. Using the measure of 50°, we can find the measure of the other angle.
90+50=140
180-140=40
The measure of the other angle is 40.
I hope I helped :)
The height of the umbrella would be 8 feet. Going by the 45, 45, 90° rule, the legs would be equal sizes which would make the height 8 feet.
We have y - 2 = m(x + 5), where m = (-1 - 2)/(10 + 5) = -3/15 = -1/5;
Then y - 2 = (-1/5)(x + 5);
5y - 10 = (-1)(x + 5);
5y - 10 = -x - 5;
x + 5y - 5 = 0 is the equation of the line.
