Answer: a = 18

explanation:
2(a + 10) = 56 -> distribute the 2
2a + 20 = 56 -> subtract 20 from both sides
2a = 56 - 20
2a = 36 -> divide both sides by 2
a = 18

Find sin 0, where is the angle shown.<br> Give an exact value, not a decimal approximation.
Nata [24]

Answer:

\displaystyle \sin\theta=\frac{12}{13}

Step-by-step explanation:

Recall that in a right triangle, sine is the ratio of the opposite side to the hypotenuse:

\displaystyle \sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}

We are actually not given the opposite side in this case. However, since we know the hypotenuse and the adjacent side, we can use the Pythagorean Theorem to find the opposite side. So:

a^2+b^2=c^2

Let <em>a</em> be the adjacent side and <em>b</em> be the opposite side. <em>c</em> will be the hypotenuse.

Substitute:

(5)^2+b^2=(13)^2

Solve for <em>b: </em>

<em />b=\sqrt{169-25}=\sqrt{144}=12<em />

So, the opposite side measures 12.

Then sine will be:

\displaystyle \sin\theta=\frac{12}{13}

Willis bought a gallon of paint.He painted a wall that is 9 feet high and 10 feet wide.Then he used he rest of the paint to pain
Otrada [13]
First you need to find the surface area of the wall that was painted, and then add the additional area in the hallway that was painted. 

The wall that was painted was 9 feet by 10 feet, or 90 square feet. 90 square feet plus the additional 46 square feet in the hallway is 136 square feet, which is the total area that the paint covered. 

Therefore the solution is 136 square feet.
