Answer:

cos(52°) = 18/x

x = 18·sec(52°)

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

Cos = Adjacent/Hypotenuse

In this geometry, that means ...

cos(52°) = 18/x

You can use the relation sec(x) = 1/cos(x) to rewrite this as ...

x = 18·sec(52°)

_____

You can also use the complementary angle and the complementary trig function.

sin(90° -52°) = 18/x

What is the estimate of the sum of 6/10 + 7/12

aleksandr82 [10.1K]

71/60. You change the denominators(bottom numbers) to 60 because that is the smallest number that both 10 and 12 can go into. Then you just add.

Use the midpoint formula to find the midpoint between H(3, 9) and J(9, -2).

TiliK225 [7]

Hello!

The midpoint formula is basically an average of x and y.

It is also written as: $(\frac{x_{1}+x_{2}} {2},\frac{y_{1}+ y_{2}} {2})$ .

With the formula above, we can substitute the given points into the equation, and simplify.

$(\frac{3 +9}{2}, \frac{9+(-2)}{2}) = (\frac{12}{2}, \frac{7}{2}) = (6, 3.5)$

Therefore, the midpoint between points H and J is choice D, (6, 3.5).
