Question

One angle of a right traingle measures 40 .what is the measure of the acute angle

Answer 1

50

Explanation:

90= right side

40= acute side

180 - (90+ 40)= 50.

Answer 2

50 degrees

Explanation:

let's take the triangle to be right angled at b

so b=90 1

and c=40 (assumption) 2

so a+b+c=180(angle sum property)

from 1 and 2

a+90+40=180

a=180-130

therefore a=50
