One angle in a right triangle measures 15 degrees. what is the measure of the other acute angle in this triangle?

A) 65 degrees

B) 75degrees

C) 105degrees

Angles add up to 180

if right triangle, one angle is 90

another is 15 as given therefor

180=15+90+x

180=105+x

subtract 105

75=x

angle is 75 degrees

answer s B

because all triangles angles add up to equal 180, and a right triangle has a 90 degree angle. you subtract 90 and 15 from 180 and that number will be the size of the remaining angle

180-90=90

90-15 = 75

the answer is B) 75degrees
