Answer:
the base of the ramp is 31 inches long.
Step-by-step explanation:
c = a/sin(α)
= 33.48514
b = √c2 - a2
= √33.4851373155042 - 122
= √977.25442103816
= 31.26107
Answer:
angle P congruent to angle N
Step-by-step explanation:
You know the angles at Q are congruent.
If angle P is congruent to angle N, then angle R is congruent to angle D.
Then both triangles are similar.
5.70c + 9.80a = 1526.60
a = 4c
5.70c + 9.80(4c) = 1526.60
5.70c + 39.20c = 1526.60
44.90c = 1526.60
c = 1526.60/44.90
c = 34 <=== child tickets sold
a = 4c
a = 4(34)
a = 136 ...adult tickets sold
Plug in the points and see if y and x are equal to each other.
(2,3)
y= x-1
3= 2-1
3= 1 (not the solution)
y=3x
3=3*3
3=9 (not the solution)
y=x+1
3=2+1
3=3 (solution) We can check to make sure.
y=-3x
3=-3*3
3=-9 (not the solution)
y=x+1 <em>is the answer.
</em>
I hope this helps!
