Question

In a triangle the largest angle is 5 0 more than four times its smallest angle . The third

angle is twice the smallest angle .

a) What is the sum of the angles of a triangle ?

b) Find the angles ?​

Answer 1

Step-by-step explanation:

The sum of angle is 100

first angle is 50 and two angle is 25-25

please follow me

Answer 2

Sum of angles of any triangle is 180°

a) 180°

b) Let smallest angle be 'x'

Then, largest angle is '4x + 50'

Then, third angle is '2x'

Then, x + 4x + 50 + 2x = 180

7x + 50 = 180

7x = 180 - 50

7x = 130

x = (130/7)°

= 18. 5°

Largest angle = ( 4× 18. 5) + 50

= 74 + 50

= 124°
