Answer:
17.0
Step-by-step explanation:
If you take the sin(39) or cos(51), it is equal to BC/27. Multiply by 27 on both sides to get 27cos(51) or 27sin(39)= x. Plug into the calculator, and voila.
Answer:
18.=400%
Step-by-step explanation:
80/20 we get 4 then we multiple 4 ×100 we get 400 and we check the answer 400% ×20 =80
Answer:
7(2 + y)
Step-by-step explanation:
2 more than y:
2 + y
Product... and 7
2 + y × 7
Simplify it.
7(2 + y)
Answer:
169 
Step-by-step explanation:
Ok so we know that perimeter is when you add up all the side lengths of a given shape. Since we know it's 52, we can use that to help us!
A square means that all 4 sides are equal; all 4 side lengths are equal...
Now we can divide the perimeter by 4 (a square has 4 sides) to get the side lengths for one side of the square (when we get one side, we automatically have the other sides)
52 ÷ 4 = 13
The side lengths for the square is 13
Check...
13 + 13 + 13 + 13 = 52 CORRECT
Now that we have the side of the square, we can find the area...
A = b * h
A = 13 * 13
A = 169 
The area of the square is 169 
Hope this helped!
Have a supercalifragilisticexpialidocious day!
