Answer:

C) 65°

Step-by-step explanation:

The relevant trig relation is ...

Cos = Adjacent/Hypotenuse

cos(?) = 25/59

? = arccos(25/59) ≈ 64.93°

The indicated angle is about 65°.

_____

You can see that the figure is drawn approximately to scale and that the angle is more than 45°. (The unmarked leg is longer than the given leg.) The only answer choice that is more than 45° is the one shown above.

Mnenie [13.5K]

Answer:

Set the larger number as x

"A number, y, is equal to the difference of a larger number and 3."

$y=x-3$

You can rearrange this equation to find the matching answer choice:

$y-x=-3\\x-y=3$

"The same number is one third of the sum of the larger number and 9."

$y=\frac{1}{3} (x+9)$

You can rearrange this equation to find the matching answer choice:

$y=\frac{1}{3} x+3\\3y=x+9\\3y-x=9\\x-3y=-9$

Find the area of the figure

Amanda [17]

Answer:

A ≈ 26.42

Step-by-step explanation:

The shape presented is a circle, and the formula for this is:

A = π $r^2$

The " $r$ ," is the radius (2.9), so plug this into the formula:

A = π $(2.9)^2$

A = π8.41

A ≈ 26.42
