Is anyone good at paralleligram?!I will mark brainlest.for 13 points​
Black_prince [1.1K]

Answer:

Y= 15

x = 12

Step-by-step explanation:

Okay, so the sides that are across from eachother, are always equal to eachother, in a parallelogram.

So, 5y-20 = 2y + 25

Next, you add 20 to both sides, and then subtract 2 from the right side, and subtract 2 from the left side ,and you get 3y = 45

divide 45 by 3 , and you get 15.

DO the same thing for the X's.

My last function question. Please break this down for me. Brainliest answer will be given
cupoosta [38]
Remember these two combinations: logab=loga+logb, log(a/b)=loga-logb
3logx=logx^3
(1/2)log(x+2)=log(x+2)^(1/2)
2log(z-4)=log(z-4)^2
so the given expression can be combined into log{[(x^3)(z-4)^2]/(x+2)^(1/2)}

Every triangle in the figure at right is equilateral. What is the measure of ∠AGE?
Andrew [12]

Answer:

120°

Step-by-step explanation:

All the angles of an equilateral triangle are equal, and hence have a measure of 60°.

∵ ∠AGF is a part of equilateral Δ AGF, m∠AGF = 60°.

∵ ∠FGE is a part of equilateral Δ AGF, m∠FGE = 60°.

Also note that ∠AGE = ∠AGF + ∠FGE.

⇒ m∠AGE = m∠AGF + m∠FGE

⇒ m∠AGE  = 60° + 60°

                    = 120°.

To the nearest tenth, which is the perimeter of ABC. Geometry
qwelly [4]

Answer:

23.6

Step-by-step explanation:

<u><em>Finding AC:</em></u>

Cos 61 = \frac{adjacent}{hypotenuse}

0.48 × 10 = Adjacent

AC = 4.8

<u><em>Now, CB:</em></u>

Cos 29 = \frac{adjacent}{hypotenuse}

0.87 × 10 = CB

CB = 8.8

<u><em>The perimeter:</em></u>

=> 10+4.8+8.8

=> 23.6
