Me. brady is putting trim around the edge of circular merry-go-round that has diameter of 15 feet. how much trim does he need to buy to the nearest tenth

47. 1 feet

Step-by-step explanation:

Brady is putting trim around the outside of the circular merry-go-round, so he needs to use the formula for circumference to find the amount of trim he needs to buy.  The formula for the circumference of a circle is:  C = dπ, where d = the measure of the diameter and π = 3.14.  Using the given measure of the diameter:

C = 15(3.14) = 47.1 feet

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.

the answer should be a. snail
