∆abc ~ ∆def. if ∠a=75° and ∠e=15°, what is the measure of ∠c?

C = 90

Step-by-step explanation:

ABC is similar to DEF

That means <A = <D

<B = <E

<C = <F

Since ABD is a triangle

A + B + C = 180

We know A = 75 and E = 15  and E = B = 15

Substituting what we know

75 + 15 + C  =180

Combine like terms

90 + C = 180

Subtract 90 from each side

90-90 +C = 180-90

C = 90

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set
