Answer:
x = 15
Step-by-step explanation:
<u>If angles are complimentary, they add up to 90 degrees</u>
<u />
<u>Step 1: Make an equation</u>
<em>x + (3x + 30) = 90</em>
<em />
<u>Step 2: Solve for x</u>
x + (3x + 30) = 90
x + 3x + 30 = 90
4x + 30 - 30 = 90 - 30
4x / 4 = 60 / 4
<em>x = 15</em>

Answer: x = 15
To answer this problem, let p be the price of each scrub. The total bill (t) is the sum of the price of the potting soil (s) and of the 9 scrubs (n). This is depicted in the equation,
$11.50 + 9p = $94.75
The value of p from the equation is 9.25. Thus, each scrub costs $9.25. The answer is letter C.
Сorrect statements:
1. EF is the longest side
2. DF = 6 cm (in a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse. )
3. <span>By the Pythagorean theorem:
DE = </span>√(12²-6²) = √(144-36) = √108 = 6√3
DE = 6√3 cm

Step-by-step explanation:
Adam is building birdhouses that requires 
i.e 0.5 feet long boards.
Now, he has an 
i.e. 8.25 feet longboard and wants to cut each 0.5 feet longboards.
We have to calculate the number of pieces of exactly 0.5 feet length that can be made from this 8.25 feet longboard.
Now, 
So, there can be 16 whole board of exact length 0.5 feet. (Answer)
