The gear ratio of two gears is the ratio of the number of teeth of the larger gear to the number of teeth of the smaller gear. in a set of three gears, the ratio of gear a to gear b is equal to the ratio of gear b to gear c. gear a has 36 teeth and gear c had 16 teeth. how many teeth does gear b have?

24 gear.

Step-by-step explanation:

It is given that .

Gear A = 36 teeth

Gear C = 16 teeth

Let gear B have x teeth.

On cross multiplication we get

Taking square root on both sides.

Therefore, gear B have 24 teeth.

14

step-by-step explanation:

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.
