PLZ Help <br> This is due by 2:20

Lana71 [14]

Answer:

The answer is 60 degrees.

Step-by-step explanation:

The three angles in any triangle add up to 180 degrees.

You know by the box at the bottom right that it's a right triangle and therefore that angle is 90 degrees. They also give you the 30 degree angle at the bottom left. So:

90 degrees + 30 degrees = 120 degrees.

180 degrees (total) - 120 degrees (first 2 angles) = 60 degrees (missing angle)

If f(x) = StartFraction x Over 2 EndFraction + 8, what is f(x) when x = 10?

goldfiish [28.3K]

Answer:

Step-by-step explanation:

$f(x) = \dfrac{x}{2} + 8$

$f(10) = \dfrac{10}{2} + 8$

$f(10) = 5 + 8$

$f(10) = 13$

How to solve 45y to the second power plus 15y minus 10 ?

Lerok [7]

Answer:

Either y = $\frac{-2}{3}$ or, y = $\frac{1}{3}$

Step-by-step explanation:

We have to solve the following quadratic equation

45y² + 15y - 10 =0

Now, dividing both sides with 5 we get, 9y² + 3y -2 =0

Hence, to solve the above equation we have to factorize the left-hand part of the equation.

So, 9y² + 3y - 2 =0

⇒ 9y² +6y -3y -2 =0

⇒ (3y +2) (3y -1 ) =0

⇒ Either (3y +2) =0 or (3y -1) =0

⇒ Either y = $\frac{-2}{3}$ or, y = $\frac{1}{3}$ (Answer)
