What is the area of this trapezoid

The area of given trapezoid = 80 square units

Step-by-step explanation:

Formula:

Area of trapezoid = h/2(a + b)

h - Height of trapezoid

a and b are the parallel bases of trapezoid.

To find the area of trapezoid

here a = 17, b = 3 and h = 8

Area =  h/2(a + b)

= 8/2(17 + 3) = 4 * 20 = 80 square units

Therefore area of given trapezoid = 80 square units

the thermometer is precise but not accurate

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.
