Question

in a triangle one angle is 69° what are the other 2 angles if they in the ratio of 1:2 answer in detail showing steps plsh​

Answer 1

Answer:

Other 2angles are 37° and 74°

Step-by-step explanation:

Sum of 3 angles of a triangle is 180°

Already one angle is given that is 69°

180°-69° = 111°

Sum of other 2 angles of a triangle is 111°

1:2 ratio of 111° is 37° and 74°

Answer 2

Sol: the sum of three angles in a triangle is 180 degree

So, if first angle is 69 degree and the other two angles are in the ratio of 1:2 then , let first angle be X

Then, second angle 2x

69°+X+2x=180°

69°+3x =180

3x=180°-69°

3x= 111°

X=111°÷3

X= 37°

2x = 37 ×2

2x= 74°
