Steve props a ladder against a wall of a building so that the he can get to the roof and throw water balloons at pedestrians. If the angle of elevation from the bottom of the
Aladder to the roof is 60°, and the building is 35 feet tall, how long must the ladder be
to the nearest tenth of a foot?

30 ft

Step-by-step explanation:

you use 35x sin(60) because 35 is the hypotenuse and the angle is 60 degrees

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
