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 – 49 = 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.
