Answer:

45

Step-by-step explanation:

You already solved that the 2 angles of the triangle are 55° and since all of the angles are on a straight line, they add up to 180°

and the equation becomes...

3x-10+55=180

3x+45=180

Subtract 45 from both sides

3x=135

Divide by 3

x= 45

Then to double check you plug 45 as the value of x in.

3(45)-10+55=180

135-10+55=180

125+55=180

180=180

Select the domain and range of F. F = {(x, y ) | x + y = 10}. Domain: {10} Range: {10} Set F is not a function and does not cont
sertanlavr [38]

Answer:

Domain: All Real Numbers

Range: All Real Numbers

Step-by-step explanation:

F is

F = {(x, y ) | x + y = 10}

(x,y) is the ordered pair

x + y = 10  is the expression

We can rearrange it

y = 10 - x

And then we can plot it using a graphing calculator. See attached image

By looking at the plot and examining the expression, we can see that there are no restrictions over x or y.

This means that the domain and range are all real numbers

Domain: All Real Numbers

Range: All Real Numbers

F is a function because it is a relation that associates each element x to a single element y.

Find the missing angels in the parallelogram
krek1111 [17]

Answer:

m<B = 60°

m<C = 60°

m<F = 80°

m<G = 80°

Step-by-step explanation:

m<B = 180° - 120° = 60°

m<C = m<B = 60° (Vertically opposite angles are equal)

m<F = 180° - (40° + m<C(60°)) = 80°

m<G = 180° - (m<H + m<B) = 180° - (40° + 60°) = 80°
