The ratio of the angle measures of the acute angles in a right triangle is 1:2 . What is the measures of these angles a. 30 and 60 b. 45 and 90 c. 60 and 120 d. 10 and 20
a triangle has 3 angles, together they add up to 190 degrees.
in a right triangle there is one angle that is 90 degrees, meaning the other two add up to 90 degrees.
the ratio between them is 1:2
a 1/3 of 90 is 30 degrees
meaning one angle is 1*30= 30 and the second is 2*30=60
-> the correct answer is "a"
