Answer:
cot α = 1/tan α = 1/2.4 = 0.42
Step-by-step explanation:
cot α=0.42
sin α = 0.92
we know that cot α = 1/tan α
thus,
cot α = 1/tan α = 1/2.4 = 0.42
we know that
sin(x)=tan(x)1+tan2(x)√
![\ sin(\alpha )=tan(\alpha )/\sqrt{ 1+tan^2(\alpha )} \\sin(\alpha )= 2.4/\sqrt{1+2.4^2} = 2.4/\sqrt{1+5.76}\\sin(\alpha )= 2.4/\sqrt{6.76} = 2.4/2.6 = 12/13 = 0.92](https://tex.z-dn.net/?f=%5C%20sin%28%5Calpha%20%29%3Dtan%28%5Calpha%20%29%2F%5Csqrt%7B%201%2Btan%5E2%28%5Calpha%20%29%7D%20%5C%5Csin%28%5Calpha%20%29%3D%202.4%2F%5Csqrt%7B1%2B2.4%5E2%7D%20%20%3D%202.4%2F%5Csqrt%7B1%2B5.76%7D%5C%5Csin%28%5Calpha%20%29%3D%202.4%2F%5Csqrt%7B6.76%7D%20%3D%202.4%2F2.6%20%3D%2012%2F13%20%3D%200.92)
sin α = 0.92
Answer:
279 × 7 ≈ 2800
Step-by-step explanation:
if you have to round to the tens place, then both would be rounded up, the 7 to 10 and the 279 to 280. 10 × 280 = 2800
Answer:
3x²y+0.5y+1
Step-by-step explanation:
2+3x²y -0.5y+y -1
2 and -1 is 1
-0.5y and +y is +0.5y so the answer is...
Answer:
I don't understood this question sorry
I think its 230 because J to G is a straight 180 degree line which means the circle is cut in half which means that jfg is 180, and we can find f to g because its 180-127 which gets us 53, and since F to I and J to G are straight lines I believe that means the opposing angle J to I is also 53 meaning you can take 180-77-53 and get G to H and add that to the 180 you got from JFG and get 230
