Question

solve the problem please​

Answer 1

Step-by-step explanation:

From the triangle ABC

Consider ∠A=60 ,∠B:∠C=5:7

In a triangle

∠A+∠B+∠∠C=180

Substituting the value

60 +∠B+∠C=180

By further calculation

∠B+∠C=180 –60 =120

Take ∠B=5x and ∠C=7x

Substituting the values

5x+7x=120

12x=120

x=120 /12=10

So we get

∠B=5x=5××10 =50

∠C=7x=7××10 =70

Answer 2

Answer:

From the triangle ABC:-

Consider ∠A=60° ,∠B:∠C=5:7

In a triangle

∠A+∠B+∠C=180 ∘

Substituting the values

60 +∠B+∠C=180 °

By further calculation

∠B+∠C = 180 –60

=120 ∘

Take ∠B=5x and ∠C=7x

Substituting the values

5x+7x=120 °

12x=120 °

x=120 /12=10

So we get,

∠B=5x=5×10

=50 °

∘

∠C=7x=7×10

=70°

Therefore, one angle is 50° and the other is 70°
