Can someone ! , evaluate the expression 3 (7 - 4) ➗ 9

i need it in detail

your answer is 1

Step-by-step explanation:

you have to first distribute your 3 to the parentheses, which gives you (21-12) so you are then going to subtract 12 from 21. and you get 9. 9 divided by 9 equals 1 so your answer is 1.

(21-12)/9

9/9

1

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.

r = 78539458390583095803458309458039485093485 or just 3
