4. An exdenior angle of a triangle is 130° and one of the interior opposite angles is 45° F
the other two angles of the triangle.
5. One of the acute angles in a right triangle is 60°. Find the other acute angle.
zle is equal to the sum of the other two, show that the triangle is right-angled​

Answer 1

Answer:

when exterior angle is 130, the corresponding interior angle will be 180 - 130 = 50

another interior angle = 45

so the third angle will be 180 - (50+45) =

180-95 = 85
