An advertising firm is going to hang banners on the side of a building. They have a 20 ft. ladder that they can lean against the wall. Safety laws only allow the company to place the ladder with a 40° angle of elevation from the ground. How high up the side of the building can the ladder reach at that angle? Round to the nearest foot.

is there a picture

step-by-step explanation:

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

16.9 times 2.85

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
