Answer:

The correct option is a.

Step-by-step explanation:

Given: ∠1 and ∠2 are supplementary angles.

Prove: l║m

Proof:

It is given that ∠1 and ∠2 are supplementary angles.

\angle 1+\angle 2=180^{\circ}           .... (1)

∠1 and ∠3 are supplementary angles because both angles lie on a straight line.

\angle 1+\angle 3=180^{\circ}           .... (2)

Using (1) and (2), we get

\angle 1+\angle 2=\angle 1+\angle 3

Subtract angle 1 from both the sides.

\angle 2=\angle 3

\angle 2\cong \angle 3

Since ∠2 ≅ ∠3 are corresponding angles,

l\parallel m

Hence proved.

Therefore the missing statement is \angle 2=\angle 3 and option a is correct.

a road rises 16 feet for every 50 feet of horizontal distance covered. in percent what is the grade of the road?
weeeeeb [17]

Answer:

32%

Step-by-step explanation:

The slope of the road is measured as

slope = \frac{rise}{run} = \frac{16}{50}

To express as a percentage multiply the fraction y 100% , that is

slope = \frac{16}{50} × 100% = 16 × 2 = 32%
