In the figure given below, ∠DBC=90° and ∠DBE is one-third of ∠ABE. What is the measure of ∠CBE?

∠DBE=1/3∠ABE ---> ∠DBE/ ∠ABE=1/3>∠DBE/(∠DBE+∠ABE)=1/1+3

∠DBE=1/4 x 90=18 > ∠CBE=90 + 22.5=112.5

Step-by-step explanation:

112.5°

Step-by-step explanation:

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
