Answer:
r = 30°
Step-by-step explanation:
According to the Exterior Angle Sum Theorem, the exterior angle, which is 90°, is equal to the 2 interior angles, which are 60° and <em>r°</em>. We know that the angle next to the exterior angle is 90°, and since all angle sums add up to 180°, <em>r</em> = 30°.

Answer:
Step-by-step explanation:
Let
x ----> the measure of one angle of the triangle
y ---> the measure of the smallest angle
z ----> the measure of the third angle
we know that
The sum of the measure of the interior angles in any triangle must be equal to 180 degrees
-----> equation A
one angle is 130 degrees more than the smallest angle
----> equation B
the third angle is 3 times as large as the smallest angle
---> equation C
substitute equation B and equation C in equation A
solve for y
Find the value of x
Find the value of z
therefore
