Question

find the angles of 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 in an isosceles triangle is 1:4.​

Answer 1

Step-by-step explanation:

a)5x:3x:10x=5x+3x+10x

=18x=180

x=180/18

x=10

5(10)=50

3(10)=30

10(10)=100

hope you get it ☺️

Answer 2

Answer:

let the angles of triangle are 5x , 3x, 10x

so, 5x + 3x + 10x = 180 ( sum of all angles of triangle)

18x = 180

x = 180/18

x = 10

so, the angles are :- 5x = 5 x 10 = 50

3x = 3 x 10 = 30

10x = 10 x 10 = 100

b:- let base angles are 1x and 4x

and the third angle be x

so, 1x + 4x + x = 180 ( sum of all angles )

6x = 180

x = 180/6

x = 30

so the angles are :-

1x = 1 x 30 = 30

4x = 4 x 30 = 120

x = 30
