If δabc is similar to δdef, the m∠a = 50°, and m∠e = 70°, what is m∠c?
a) 60°
b) 70°
c) 90°
d) 120°

A)

Step-by-step explanation:

Given: ΔABC is similar to ΔDEF

Therefore,

∠A=∠D=50°

∠B=∠E=70°

∠C=∠F

Using Angle sum property, in triangle ABC, we get

The angle sum property of a triangle says that, the sum of all the angles in a triangle is .

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!
