What is the LCM of
12 and 40

120

Step-by-step explanation:

12 and 40

Multiples of 12 = 12,24,36,48,60,72784,96,108,120..

Multiples of 40 = 40,80,120..

Common in both = 120

120

Explanation:

The least common multiple (LCM) of two or more whole numbers is the smallest whole number that is divisible by each of those numbers. Basically, the LCM is the smallest number that all the numbers divide into evenly. So for 12 and 40, we get 120 since 120 ÷ 12 = 10, 120 ÷ 40 = 30

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.
