Answer:
Zx = 24 degrees
Step-by-step explanation:
since it is supplementary it adds up to 180 degrees. so you have part of the angle (156 degrees) so the equation would be 180 - 156 = Zx (origionally Zx + 156 = 180).
Answer: ≅37.68
Step-by-step explanation: The formula for circumference is πd. pi is equal to 3.14, so 3.14 x 12 is ≅37.68

___________________________

p(A) = 40/55
p(B) = 15/55

Therefore,




Answer:
y + 3 = -1/4(x - 8)
Step-by-step explanation:
I think I answered your question before.
The point slope formula is:
y - y₀ = m(x - x₀), where m=slope and (x₀, y₀) are the points on the graph.
They gave you (8, -3) for your (x₀, y₀), and m=-1/4.
x₀=8 and y₀=-3 in this case.
Just plug it into the equation
y - y₀ = m(x - x₀)
y - (-3) = (-1/4)(x - (8))
y + 3 = -1/4(x - 8)
Answer:
Step-by-step explanation:
take angle A as reference angle
using sec rule
sec A=hypotenuse/adjacent
sec A=13/5
sec A=2.6
A=68 degree
for ratio,
sec A=13/5
