Harvey is taking a test with 45 questions on it. He needs to make at least 80% on the test. Which equation can he use to determine the greatest number of questions he can get wrong and still make an 80?
A 80/100 = X/25

B 20/100 = X/45

C 100 - 45 = x
D 100 - 80 + 45 = x

answer: procent 54 wynosi 33,33%

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.

answer is 33

step-by-step explanation:

i think the length is 12 and the width is 17
