Question

the measure of one acute angle in a right triangle is 38 degrees . what is the measure of other acute angle in that triangle
A.32 degrees
B.42 degrees
C.52 degrees
D.62 degrees

Answer 1

A right triangle has to have 1 90 degree angle
All angles inside a triangle must add up to 180 degrees

90 + 38 = 128
180 - 128 = 52

answer is C

Answer 2

Measure of the other acute angle in the right angled triangle is equals to 52degrees.

What is triangle?

" Triangle is defined as the two dimensional closed shape with three sides , three vertices and three angles enclosed in it. sum of the measure of all the three angles in a triangle is equals to 180°."

According to the question,

Given triangle is right triangle.

ΔABC  represents the given right triangle.

∠A represents right angle

∠B represents the given acute angle with measure 38 degrees.

Therefore in triangle ABC we have,

∠A + ∠B + ∠C = 180°

Substitute the given values of the angles we get,

90° + 38° + ∠C = 180°

⇒128° + ∠C = 180°

⇒ ∠C = 180° - 128°

⇒ ∠C = 52°

Hence, Option(C) is the correct answer.
