Hello!

As you can see, the angle is a straight angle, which measures 180°. One angle measures 80°.

180 - 80 = 100

That means the rest added all together measure 100°.

3x + 2x = 5x

5x = 100

Divide both sides by 5

$\frac{5x}{5} = \frac{100}{5}$

$\framebox{x = 20 \°}$

Answer:

<h2>Total yards of ribbon bought is 6.993yards of ribbon</h2>

Step-by-step explanation:

Total pieces of ribbon James bought for his craft project = 10pieces. If each pieces of ribbon were 2.1feet long, the total number of feet for 10ribbons is expressed as;

$= 10 * 2.1\\= 21feets$

Converting 21 feets to yards;

1 feet = 0.333yard

21feets = x

x = $21feet * 0.333\\= 6.993yards$

Total yards of ribbon bought is 6.993yards of ribbon
