Answer:

32

Step-by-step explanation:

let a = 5

a² + 7 | Original equation

5² + 7 | Substitution of a as 5

25 + 7 | 5 to the power of 2 is 25, as 5*5 = 25.

32       | 25 + 7 = 32

Find the measure of angle x in the figure below<br><br>A.35°<br>B.47°<br>C.51°<br>D.62°
Dafna11 [192]
First of all, we know that a line is 180°. This means if we add the angles of 61°, 57°, and angle y, we should get 180<span>°.

\sf 61\textdegree +57\textdegree+y=180\textdegree

Simplify:

\sf 118\textdegree +y=180\textdegree

Subtract 118° to both sides:

\sf y=62\textdegree

We also know that all three angles of a triangle add up to 180<span>°. So we have:

\sf 67\textdegree+62\textdegree +x=180\textdegree

Simplify:

\sf 129\textdegree +x=180\textdegree

Subtract 129° to both sides:

\sf x=\boxed{\sf 51\textdegree}

astraxan [27]
8x-9y=19
4x+y=-7
 Multiply all terms of the 2nd by (9)===>  36x + 9y= 63

add (36x  9y=  63) to the 1st ===> 44x+0y = -44 ===> x=-1
replace x by this value in any of the equation & you'll get y=-3
