Let the ladder length be L, then
sin 70 = 20/L, L = 20/sin70 = 21.3 feet
the length of ladder is 21.3 feet
Answer/Step-by-step explanation:
Given:
m<MNQ = 132°
m<Q = 54°
m<P = 3x
1. m<MNQ = m<P + m<Q
Reason: exterior angle theorem of a triangle
Plug in the values
2. 132° = 3x + 54°
Reason: Substitution
3. x = 26
Reason: Algebra
132 - 54 = 3x (substraction property of equality)
78 = 3x
78/3 = x (division property of equality)
26 = x
x = 26

Answer:
Slope =-1/4
Step-by-step explanation:
y=mx+n
Slope=m=(y2-y1)/(x2-x1)
A(-1,19).... x1 =-1, y1=19
B(11,16)..... x2=11, y2=16
Slope=(16-19)/(11-(-1))=(-3)/(11+1)=-3/12=-1/4
