Can someone check my answers to see if they're correct?
Sati [7]

Answer:

a = 125°

b = 55°

c = 55°

d = 55°

e = 125°

f = 55°

Step-by-step explanation:

See the attached diagram.

The angles (x + 75)° and (2x + 25)° are the alternate angles and they are equal.

So, x + 75 = 2x + 25  

⇒ x = 50

Hence, (x + 75)° = (50 + 75)° = 125°.

Now, from the given diagram it is clear that  

a = (x + 75)° = (2x + 25)° = e = 125°

And, b = c = d = f = 55°

This is because, a and b are supplementary angles and their sum will be 180°.

So, a + b = 180°

⇒ 125° + b = 180°

⇒ b = 55°

So, b = c = d = f = 55° (Answer)

Which congruence theorem can be used to prove<br> ABR = RCA?
vivado [14]

Answer: The HL Theorem can be used to prove ABR ≅ RCA because both triangles share the same hypotenuse and a leg. The HL theorem states that If the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

How do I do this problem?
goldenfox [79]

so a quadrilateral is a figure with 4 sides. So looking at the picture I see 5 rhombi and 7 squares. So all together thats 12 quadrilaterals  

So to find the ration you have to do:

amount of thing: whole

so in this case it would be

12:24

which you can simplify

normally you'd simplify to 1:2 but that doesn't seem like an option so I'd go with the one closest to that ratio
