Answer:
Step-by-step explanation:
No you are correct. That's the correct end result. Technically you should start with
Area = s^2
Area = 64 ft^2
s^2 = 64
sqrt(s^2) = sqrt(64)
s = 8
s = - 8 has no meaning.
Your way is fine.
Replace the y with 0, and then solve for x.
Answer:
R = 25.8
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos R = adj side / hyp
cos R = 9/10
Taking the inverse cos of each side
cos ^-1 ( cos R) = cos^ -1 ( 9/10)
R=25.84193
Rounding to the nearest tenth
R = 25.8
