Simplify:

4f – 15s + 16f – 20 + 17 – 12f

8f-15s-3

Step-by-step explanation:

Combine the like terms. 4f plus 16f is 20f. 20f minus 12f is 8f. There are no like terms for 15s so it stays. Finally, combine -20 and 17 and you get -3. So the answer is 8f - 15s - 3.

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.
