Question

find the angle of a triangle in the following cases. (a)the angles are in the ratio 5:3:10 .(b) the ratio of the base angle to the other angle is an isosceles triangle is 1:4.​

Answer 1

Answer: look at the step by step explanation

Step-by-step explanation:

let angles be 3x, 5x, 10x

3x+5x+10x=180(angle sum property)

18x=180

x=180/18

x=10

therefore, angles are 3*10=30

5*10=50

10*10=100

b) isosceles triangle has 2 sides equal

so let the angles be 1x,5x,1x

1x+4x+1x=180(angle sum property)

6x=180

x=180/6

x=30

1x=1*30=30

4x=4*30=120

1x=1*30=30
