Answer: If you’re looking for the area it is 650.65 yd and if you’re looking for the volume it is 1072.33
Answer: 
Step-by-step explanation:
The first step is to make the division of the fractions
and
. To do this, you can flip the fraction
over and multiply the numerators and the denominators of the fractions. Then:

Reduce the fraction
:

Now you can make the subtraction: in this case the Least Common Denominator (LCD) will be the multiplication of the denominators. Divide each denominator by the LCD and multiply this quotient by the corresponding numerator and then subtract the products. Therefore you get:

Answer:
x = 25
Step-by-step explanation:
We know that the remaining angles add up to 90°, because the right angle (triangles have 180° total.)
2x + 15 + x = 90 | Given
3x + 15 = 90 | Combine x
3x = 75 | Subtract 15
x = 25
Congrats? But maybe post a question next time so u don’t get in trouble :)
