its easy it should be 1.25 or well that the answer I got
Answer:
11 feet
Step-by-step explanation:
This is a right triangle trig problem with a little geometric twist to it. The angle of depression. If we drew this triangle and the person at the top of it and then drew in a horizontal line from his line of vision, this line of vision is parallel with the ground. The hypotenuse (escalator, here) serves as the transversal cutting these parallel lines. That means that a lot of angle congruencies exist. The angle of depression is alternate interior with the base angle of the triangle (the angle that is NOT the right angle, that is) so that makes them congruent. Therefore, we have that base angle measuring 42.51 degrees (this is the reference angle) and the length of the hypotenuse. We are looking for the height of the triangle, which is also the side across from the reference angle. The trig ratio we need to solve this has to involve the reference angle, the hypotenuse, and the side across from the reference angle. That is the sin ratio. Setting up to solve for the side across from the angle:
Solving for y:
16 sin(42.51) = y
Do this on your calculator in degree mode to get that
y = 10.8 feet, or rounding, y = 11

hhshshhy66ttwt was a good choice but I think that 55th year is a good thing for the rest and I don't think that I would be a big deal with girls but teache said something about you will be a little more holidays than I will help him to get a good thing and a good idea of what he should be my first of year to be with girls in my class work block the sixth day of
Subtract 3 both sides first. R-3=ts²
next, divide both sides by t, (R-3)/t=s²
finally, take the square root of both sides
√(R-3)/t = s. 2nd choice.
Answer:
1. Enlarge, Shrink
2. Smaller
3. Bigger
Step-by-step explanation:
Dilation is something expanding or shrinking, like how your eyes dilate.
Simply think of the scale factor as what you are multiplying the entire figure by. If you are multiplying it by let's say 2, it would double in size, thus getting larger. If you were to multiply it by 1/2, then it would decrease, or shrink, to half its original size.
