Do sin(90)*13/15 which gives you 0.87 then do inverse of sin-1(0.87) which angle A = 60.45 degrees
Because your question isn't specific or formatted exactly, I cannot guarantee that my answer is what you expect.
√2x - 1 + 2 = 5
√(2x + 1)² = 5²
2x + 1 = 25
2x = 24
/2 /2
x = 12
Therefore x = 12.
Proof:
√2x - 1 + 2 = 5
√2(12) - 1 + 2 = 5
√24 - 1 + 2 = 5
√25 = 5
5 = 5
Answer:
x= 8.4
Step-by-step explanation:
y=0.8
4x + 8y =40
4x + ( 8 x 0.8) = 40
4x + (6.4) =40
4x = 40 - 6.4
4x = 33.6
x = 8.4
Answer:
A piece of wood that is 33 1/4 inches long is cut into 3 equal pieces.
Length of each piece would be: (33 1/4)/3 =(133/4)/3 = 133/12 = ~11.08 inch
Hope this helps!

<span>hello :
</span>cot(-x) tan(x)=-1......(*)
* cot(x) = 1/tan(x)
cot(-x) = -cot(x)= -(1/tan(x))
cot(-x) tan(x) = -(1/tan(x))×tan(x)=-1
