Find the measure of the indicated angle to the nearest degree.

5) 34°    6)  17°   7)  ?    8)  ?   9)  50°   10)  ?   You do 7, 8 and 10

Step-by-step explanation:

Let x = the measure of the unknown angle in each case

5)  tan x = 10/15     arctan 10/15 = 34

6)  tan x = 10/32    arctan 10/32 = 17

7)  tan x = 3/8     You do this one

8)  tan x = 4/6     You do this one

9)  sin x = 26/34   arcsin 26/34 = 50

10)  tan x = 20/37   You do this one

You need to learn the definitions of sin, cos, tan, i.e sin x = opp/hyp

cos x = adj/hyp and tanx = opp/adj

opp means opposite side of x

adj means the leg of the right triangle that is a side of x

hyp means the hypotenuse of the right triangle

1/4 of the pizza is left over.

Explanation:
First, we want to find how much is left over. To do this, we subtract the whole pizza by how much he ate. So 8/8 - 6/8 = 2/8. Now, we have to simplify 2/8. The GCF (Greatest Common Factor) of 2 and 8 is 2, so we divide 2/2 and 8/2. We get 1/4, therefore that is the answer.
