Answer:
12) x = 49.5
13) x = 8.5
14) x = 44.8
15) x = 4.6
Step-by-step explanation:
We can solve for the missing side lengths using trigonometry
Remember these are the trigonometric ratios
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Adjacent
For #12
We can use trig ratio tangent as we are given an angle with a measure of 68° and its adjacent side length and we need to find the opposite side length. When dealing with opposite and adjacent we can use tan.
That being said we want to create an equation to solve for x

Now we solve
* multiply each side by 20 *

we're left with x = 49.5
It seems that all of the problems are dealing with an angle, its opposite side and its adjacent side. So we will use the same trig ratio "tan" and process to solve for x.
For 13)

*multiply each side by x*

*divide each side by tan(62)

we're left with x = 6.5
For 14)

multiply each side by x

divide each side by tan15

we're left with x = 44.8
For 15)

multiply each side by x

divide each side by tan(74)

we're left with x = 4.6
14 7/10 2
I do not know the rest, sorry.
Hope I helped!

Small number is 4 and the large number is 12.
12 - 4 = 8
12^2 + 4 = 144 + 4 = 148
Have a nice day sie
Answer:
$275
Step-by-step explanation:
This is what I got:
You first <u>convert</u> 2.75% into 0.0275
You then <u>multiply</u> 500 x 0.0275 = 13.75
Finally you <u>multiply</u> 13.75 x 20 = 275
so the answer should be 275
