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
Answer:
She can make 9 uniform tops from the material left.
Step-by-step explanation:
Given:
Yards of material left on the bolt = 
Material requirement for a uniform top for band members = 
To find the number of tops that can be made from the material left.
Solution:
In order to find the number of tops that can be made from
yards of material, we need to divide
by
.
Number of uniform tops that can be made is given as:
⇒ 
We first convert mixed number to fractions.
⇒ 
To divide fractions the fractions are multiplied after flipping the divisor.
⇒ 
⇒ 
⇒ 9
Thus, she can make 9 uniform tops from the material left.
Take the first 9 is in yours tens place so you want to take the second 9 and round up because anything 5 or more goes up and 4 or less stays the same
