Question

One angle of a triangle measures 60 degrees. If the other two angles are in the ratio 5:7, then find the two angles.

Answer 1

consider,
5x and 7x
5x+7x=60
12x=60
x=60÷12
x=5
therefore,5×5=25
7×5=35
the angles are 25and 35

Answer 2

Answer:

70 degree and 50 degree

Step-by-step explanation:

let the two angles be 5x and 7x

5x+7x+60 degree=180

12x+60 degree=180

12x=180-60

12x=120

x=10

therefore, 5x×10=50

7x×10=70
