We know that formula to solve for the area of a trapezoid is A=(a+b)/2+h. So, the formula to find the height would be 2*[A/(a+b)].
2*[A/(a+b)] Substitute the values for the variables
2*[25/(6+4)] Solve the parentheses
2*(25/10)
2*2.5=5
The height must be 5.
Answer:
x = 53.13
Step-by-step explanation:
sin theta = opposite side over hypotenuse
sin x = 4/5
Take the inverse sin of each side
sin ^-1 ( sin x)= sin ^-1 (4/5)
x = sin ^-1 (4/5)
x =53.13010235
To the nearest hundredth
x = 53.13
