2 right angles = 2 x 90 = 180
So, 2 right angles = 180.
Question 2.
3 right angles = _____________
Answer:
270
Explanation:
1 right angle = 90
3 right angles = 3 x 90 = 270
So, 3 right angles = 270.
Use a protractor to measure each angle.

Question 7.
∠ABC measures 34°.
∠CBD measures 113°.
What is the measure of ∠ABD?
Answer:
147°
Explanation:
∠ABC measures 34°

A wheel is turned 141° one way and then 49° the other way
141 – 49Â = x
Subtract to find
141 – 49 = 92°
The wheel stops at 92° .
Draw an angle with each measure. Use a protractor.

Question 12.
Connor has a roll of tape. He uses 2\(\frac{1}{7}\) ft to tape one present. He uses 4\(\frac{2}{7}\) ft to tape another present. Then he uses 3\(\frac{2}{7}\) feet to tape a third present. He has 14\(\frac{1}{7}\) ft of tape left over. How many feet of tape did he begin with?
Answer:
23\(\frac{6}{7}\) ft
Explanation:
Connor has a roll of tape
He uses 2\(\frac{1}{7}\) ft to tape one present
He uses 4\(\frac{2}{7}\) ft to tape another present
Then he uses 3\(\frac{2}{7}\) feet to tape a third present
He has 14\(\frac{1}{7}\) ft of tape left over
Add to find
2\(\frac{1}{7}\) + 4\(\frac{2}{7}\) + 3\(\frac{2}{7}\) + 14\(\frac{1}{7}\) = 23\(\frac{6}{7}\)
So, Connor begin with 23\(\frac{6}{7}\) ft of tape.
Question 13.
A school group goes on a field trip to the Grand Canyon. 140 people ride 7 buses. If each bus holds the same number of people, how many people are on each bus?
Answer:
20
Explanation:
A school group goes on a field trip to the Grand Canyon
140 people ride 7 buses
Each bus holds the same number of people
I use mental math to solve
I divide 140 by 7
140 / 7 = 20
So, 20 people are on each bus.
