Question

Ina triangle one angle is 90find the othere two angles xand 2x

Answer 1

Answer:

Step-by-step explanation:

in a triangle, the angles add up to 180

therefore:-

90+ x+ 2x = 180

90+3x=180

3x=90

x=90/3

x=30

2x=60

these are the two angles

Answer 2

Step-by-step explanation:

90 + x + x = 180 ( sum of int. angles of triangle is 180°)

90 + 2x = 180

x = 180-90/2

x = 90/2

x = 45

2x = 2×45

= 90
