Aquart of stain covers 100 square feet. how many quarts should you buy to stain the ramp? (assume you do not have to stain the bottom of the ramp.)

270.6  or 2.7 Quart or about 3 quart of stain.

Step-by-step explanation:

From the given example, we recall the following,

A quart of stain covers (100) square feet

Let The 30 in. be  converted to 2.5 feet

Then,

The sides:

(30 x 2.5) ÷ 2 = 37.5

37.5 + 37.5 = 75

For the Back:

2.5 x 6 = 15

Top:

30.1 x 6 = 180.6

180.6 + 75 + 15 = 270.6  or 2.7

Therefore, about 3 quarts of stain is needed

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
