Answer is A, y = 65
The top angle is 50 because 180 - 130 = 50
Since the top angle is 50, the two bottom angles have to add up to 130. Since the bottom angles are the same, you can do 130 / 2 to find the angles which equals 65.
Answer:
Q1. 1050 miles
Q2. 1h 30m
Step-by-step explanation:
Q1. 1h = 300 miles
3
h = 3.5 × 300 miles
= 1050 miles
Q2. 68km = 1h
102km = 
× 1h
= 1.5h
= 1h 30m
The x and y coordinate are switched
Scale factor: f=0.5
AB=2.2
LM=?
LM=f x AB=0.5 x 2.2 →LM=1.1
The length of LM is 1.1
Slope (m) =
ΔY
ΔX
=
4
3
= 1.3333333333333
θ =
arctan( ΔY ) + 180°
ΔX
= 233.13010235416°
ΔX = -3 – 3 = -6
ΔY = -6 – 2 = -8
Distance (d) = √ΔX2 + ΔY2 = √100 = 10
Equation of the line:
y = 4/3x – 2
When x=0, y = -2
When y=0, x = 1.5
