Answer:
sin X = 12/13
cos X = 5/13
tan X = 12/5
Step-by-step explanation:
Recall the definitions as follows:
For a right triangle (i.e one angle is 90 deg) with one of the angles X
sin X = opposite side / hypotenuse
cos X = adjacent side / hypotenuse
tan X = opposite side / adjacent side
In our case for angle A, the following applies:
opposite = 36
adjacent = 15
hypotenuse = 39
hence
sin X = opposite side / hypotenuse = 36/39 = 12/13
cos X = adjacent side / hypotenuse = 15/39 = 5/13
tan X = opposite side / adjacent side = 36 /15 = 12/5
Answer:26.9 feet
Step-by-step explanation:
SOH-CAH-TOA
\tan M = \frac{\text{opposite}}{\text{adjacent}}=\frac{74}{x}
tanM=

74
\tan 70=\frac{74}{x}
tan70=

74
x\tan 70=74
xtan70=74
Cross multiply.
\frac{x\tan 70}{\tan 70}=\frac{74}{\tan 70}

74
Divide each side by tan 70.
x=\frac{74}{\tan 70}=26.9338\approx 26.9\text{ feet}
x=

=26.9338≈26.9 feet
Type into calculator and roundto the nearest tenth of a foot.

There are 16 ounces in a pound. If there are 4 pounds, then you take 16 and multiply it by 4 and then add 6.
The answer is: 70.
Answer:
-1
Step-by-step explanation:
We know that i^4 is equal to one so what you do is divide by 4 and the remainder is your simplified version
In this case the remainder is two which means taht i^82 = i^2 = -1
