Answer: 63
Step-by-step explanation: To find 70% of 90, first write 70% as a decimal by moving the decimal point two places to the right to get .70.
Next, the word "of" means multiply, so we have (.70)(90) which is 63.
So 70% of 90 is 63.
Answer:
4608*sqrt(3)
Step-by-step explanation:
x + 2x = 3x, so 3x is the height of the triangle. This is a 90-60-30 triangle so the base would be 3x*sqrt(3). To find the area, we can multiply the base with the height and divide by two, so it would be (3x)(3x*sqrt(3))/2 or (9/2)x^2 * sqrt(3). x = 32, and plugging this into the equation gets us to (9/2)32^2 * sqrt(3), which is 4608*sqrt(3).
