Answer:

x = 10

y = 15

Step-by-step explanation:

Angles 8x - 10 and 7x are congruent because they are alternate interior angles of parallel lines cut by a transversal.

8x - 10 = 7x

x = 10

7x = 7(10) = 70

6y + 20 and 7x are supplementary since they are a linear pair.

6y + 20 + 7x = 180

6y + 20 + 70 = 180

6y = 90

y = 15

What is the value of x in the triangle?
Arturiano [62]
We can use SOH CAH TOA to solve this :)

We’re going to use Cosine because the angle and sides given are Adjacent and Hypotenuse- which goes with the CAH part of SOH CAH TOA.

Cos(18) = x/25

Multiply both sides by 25

25cos(18) = X = 23.776

So x = 23.776 cm

I hope this Helps!

PLEASE ANSWER QUICKLY WITH DESCRIPTION ON HOW TO DO IT!!! If (-a^2b3)(2ab^2)(-3b)=ka^mb^n what is the value of m+n????
iragen [17]

Answer:

m+n=9

Step-by-step explanation:

Put the equation into the form ka^mb^n by multiplying the coefficients (-1*2*-3), so k= 6, then add the exponents of a together, a^2+a^1= a^3, m=3.

Now you have 6a^3, next we do the exponents of b together, b^3, b^2, b^1= b^6, n=6.

This is 6a^3b^6. m=3 and b=6, so add m+n=9.

Marina CMI [18]
Yes! The lengths of each side must be less than the sum of the other two lengths. It looks like this:
4+4>7
7+4>4
