Question

If one angle of a right angled triangle is 70°.Then find out the measure of third angle

Answer 1

Answer:

20

Step-by-step explanation:

The sum of the angles in a triangle is always 180.

In a right-angled triangle, we have one angle as 90 and in this case one angle as 70.

Therefore, the third angle will be

180 - 90 - 70 = 20

Answer 2

70+90+x=180
x =180-160
x =20
