I dont have time to do all of these right now my apolgies but Ill explain how to do it.
The 3 angles of a triangle add up to 180.
So let me show you how to do 1.
.
.
.
1. 58 degrees
92, 30, ?
If we add together the first two angles,
92+30= 122
Knowing the total addition of all three angles would ne 180, we can subtract 122 from it to get the third angle.
180-122= 58
So we now know the last angle is 58 degrees because
92+30+58=180
10.38
i multiplied each number and the answers that i got i added them to get the area
Answer:
$33.84 cents
Step-by-step explanation:
Given the following question:
4 gallons = 15.04
1 gallon = ?
How much for 9 gallons?
To find the answer we have to find how much one-gallon costs since we already know how much it costs for 4 gallons of this unleaded gasoline.



One gallon of this gasoline costs $3.76 now we need to find how much it costs for 9 gallons.


For nine gallons of gasoline it will cost you "$33.84 cents."
Hope this helps.
The distributive property: a(b + c) = ab + ac
(-7c + 8d)0.6 = (-7c)(0.6) + (8d)(0.6) = -4.2c + 4.8d
These angles should add to 180 degrees because the angles are on a straight line so you should use the formula x=180-90-38. Therefore, x should be 52 degrees
