Question

one angle of a right angle triangle is 70° find the other acute angle​

Answer 1

Answer:

Step-by-step explanation:

A=70° (given)

B=90° ( because it is a right angled∆)

C=?

In ∆ABC,by angle sum property of a∆

A+B+C=180°

70°+90°+C=180°

160°+C=180°

C=180°-160°

C=20°

so, the other acute angle is 20°

hope this answer will help you.

Answer 2

Answer:

20°

Step-by-step explanation:

Lets take angle P , Q , R

P = 70° ,

Q = 90° ,

R = ?

now,

∠P + ∠Q + ∠R = 180°

70° + 90° + ∠R = 180°

       160° + ∠R = 180°

                  ∠R = 180° -160°

                  ∠R = 20°
