Question

(1) 209.70 (iv) 599, 45° (v) 35. 1162
Find the measures of the angles of a triangle in each of the following cases.
One of the acute angles of a right triangle is 63º. Find the other acute angle.
Hint Since it is a right tiangle, one angle = 90. So. other acute angle - 639 = 90°
a) The three angles are equal to one another.
m One of the angles is 140° and the other two angles are equal.
() One angle is twice the smallest angle and another angle is three times the smallest angle.
[Hint La be the measure of the smallest angle in degrees. Then measures of the other two angle are 2
and 31)
(s) If one angle of a triangle is 80° and the other two angles are in the ratio 3:7.
(vi) The angles are in the ratio 2:3:4​

Answer 1

Answer:

right angle and a right angle in it and the other angle is 63 so now we know two angles 90 degree and 63 degree now sum of all angles in a triangle is 180 degree so third angle is = third angle = 180 - 90 = 90 - 63 = 27
