Question

The ratio of two angles of a triangle is 1 : 2. If the other angle is a right angle, find the 80 angles of the triangle.​

Answer 1

Answer:

Pls mark me brainliest

Step-by-step explanation:

ratio = 1:2

other angle = right angle = 90 degree

Hence,

1x + 2x + 90 = 180 degree

3x + 90 = 180 degree

3x = 180 - 90 degree

3x = 90 degree

x = 90/3 = 30 degree

Then the value of x is 30 degree

Therefore,

1X = 1 x 30 = 30 degree

2X = 2 x 30 = 60 degree

Therefore, 30 + 60 + 90 = 180 degree

Formula matches right?!!
