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°

Answers

Answer 1
Answer:

Answer: A) 60^(\circ)

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

\angle{A}+\angle{B}+\angle{C}=180^(\circ)\n\n\Rightarrow\ 50^(\circ)+70^(\circ)+\angle{C}=180^(\circ)\n\n\Rightarrow\ 120^(\circ)\angle{C}+=180^(\circ)\n\n\Rightarrow\ \angle{C}=180^(\circ)-120^(\circ)\n\n\Rightarrow\ \angle{C}=60^(\circ)

The angle sum property of a triangle says that, the sum of all the angles in a triangle is 180^(\circ).
Answer 2
Answer: Ok so if they are similar that means equal angles so 50+70=120 then 180-120=60 so the answer is A. #TeamAlvaxic

How do you find a side length of a cube with the surface area of one face (64cm)

Answers

Fact #1:
A cube has six faces.

Fact #2:
Every one of them has the same area.

Fact #3:
The surface area of each face is (the length of the cube's side)²

Now that I look at this one more carefully, the only thing you need to know
to solve it is Fact #3.  (But you can keep the others and save them for later.)

The surface area of each face is (the length of the cube's side)²

64 is the (length of the cube's side)²

Can you find a number that gives you 64 when you multiply it by itself ?
That's the length of the cube's side.

Hint: If you don't get ' 8 ', work on it a little more.

45° I think because 45° is half of 90° and no polygon interior angle is less than 90°
