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

A triangle has one side measuring 16 inches and two sides measuring 13 inches. Is this triangle scalene?

nadya68 [22]

No, because a scalene triangle has to have all sides that are different lengths. 2 sides being 13 inches would mean that the triangle has 2 sides that are equal, making it an isosceles triangle.

Eduardo has a recipe that uses 2/3 cup of flour for each batch. If he makes 4 batches, how many cups of flour will he need? How

34kurt

Answer:

4 batches: $2\frac{2}{3}$ cups

7 batches: $4\frac{2}{3}$ cups

Step-by-step explanation:

If he uses 2/3 cup of flour for <u>each</u> batch, then that is 2/3 four times, or 2/3 · 4.

$\frac{2}{3}$ × $\frac{4}{1}$

= $\frac{8}{3}$ = $2\frac{2}{3}$

If he makes three more, than that will be 7 batches in total. We can multiply 2/3 by 3 to find out how much will be needed for those extra three, then add that product to $2\frac{2}{3}$ .

$\frac{2}{3}$ × $\frac{3}{1}$

= $\frac{6}{3}$ = 2

$2\frac{2}{3} +2$ = $4\frac{2}{3}$

Thus, $2\frac{2}{3}$ and $4\frac{2}{3}$ are the answers.

hope this helps!
