Question

The acute angles of a right angled triangle are in the ratio of 3:4. Find all the angles of the triangle ?​

Answer 1

Answer:

Step-by-step explanation:

m∠C = 90°

m∠A = (3x)°

m∠B = (4x)°

(3x)° + (4x)° = 90°

7x = 90

x = $\frac{90}{7}$

m∠A = ( $\frac{270}{7}$ )° ≈ 39°

m∠B = ( $\frac{360}{7}$ )° ≈ 51°

Answer 2

Answer:

3 4

90 + 3 + 4=180

7 +90=180

7=180-90

7=90

=90/7

12.8571429

3=3(12.8571429) =38.6

4 = ( 12.8571429) =51.4
