Answer:
½ asin x + ½ x √(1−x²) + C
Step-by-step explanation:
You're going in the right direction. The next step is to use a power reduction formula:
∫ cos² u du
∫ (½ + ½ cos(2u)) du
½ ∫ du + ½ ∫ cos(2u) du
½ ∫ du + ¼ ∫ 2 cos(2u) du
½ u + ¼ sin(2u) + C
Next, we use double angle formula:
½ u + ½ sin u cos u + C
x = sin u, so u = asin x, and cos u = √(1−x²).
½ asin x + ½ x √(1−x²) + C
I think the equation is y=5+2x
The answer is C
because the only side that would work to make ASA is C, A would just make it SAA
ps i had geometry last year and these type of problems were easiest in my opinion so if you have any questions feel free to ask :)
Step-by-step explanation:
angle S + angle W + angle STW = 180
(7x + 6) + (7x + 1) + angle STW = 180
So angle STW = 180 - (7x + 6) - (7x + 1)
angle STW + angle STP = 180 (straight angle = 180)
180 - (7x + 6) - (7x + 1) + angle STP = 180
angle STP = 180 - 180 + (7x + 6) + (7x + 1)
= 7x + 6 + 7x + 1
= 14x + 7
15x = 14x + 7
x = 7
angle STP = 15x = 15(7) = 105
