The area of the frame would be 19.25’
Answer:
(5h-4t)(5h+4t)
Step-by-step explanation:
25h² - 16t²
adding and subtracting 20ht from it (√25 and √16 = 5x4 = 20):
25h² + 20ht - 20ht -16t²
factor:
(5h-4t)(5h+4t)
If you're taking trig, the "sum and difference formulas for trig functions" are basic facts that you'll need to learn and commit to memory. I'd suggest you look up these formulas on the net. You will likely immediately find listings for the sine, cosine and tangent.
Answer:
5π/6
Step-by-step explanation:
Subtract multiples of 2π until you find the angle in the desired range.
41π/6 -36π/6 = 5π/6
The angle 5π/6 is co-terminal with 41π/6.
