The perimeter of a rectangular field is 328 yards. If the length of the field is 89 yards, what is its width?
miv72 [106K]

<u>Set up an equation based on the information given</u>

89 + 89 + x + x = 328

<u>Combine like terms</u>

89 + 89 = 178

x + x = 2x

2x + 178 = 328

<u>Solve</u>

2x + 178 = 328

328 - 178 = 150

2x = 150

x = 75

Answer

The width of the rectangular field is 75 yards.

Solve the unknown angle measure?<br><br>Help Any1 ASAP! Will Mark Brainliest!
zlopas [31]

Answer:

X=40°

X=30°

X=50°

Step-by-step explanation:

Let our unknown angles be denoted by X

Part I

We are given the sum of the angles as 70°, the known as 30° and the unknown as X;

To find X, we subtract the known angle from the sum as:

X=70°-30°=40°

Hence X= 40°

Part II

We are given the sum of the angles as 70°, the known as 40° and the unknown as X;

To find X, we subtract the known angle from the sum as:

X=70°-40°=30°

Hence X= 30°

Part III

We are given the sum of the angles as 80°, the known as 30° and the unknown as X;

To find X, we subtract the known angle from the sum as:

X=80°-30°=50°

Hence X= 50°
