Answer:AGC and DGH are opposite angles.
Step-by-step explanation:
So, Y+10=3x-40
Y-3x=-50-(1)
3x-40=2x
3x-2x=40
x=40
Y-3x40=-50
y-120=-50
y=-50+120
y=70
Hence, the answer is A 70°
Answer:
Speed of wind = 23.63 miles per hour
Plane speed in still air = 260 miles per hour
Step-by-step explanation:
Given:
Time taken with wind = 5 hour
Time taken against wind = 6 hour
Assume;
Speed of wind = s
So,
Speed of Plane with wind = (260 + s) miles per hour
Speed of Plane against wind = (260 - s) miles per hour
Distance = speed x time
So,
(260 + s)5 = (260 - s)6
1,300 + 5s = 1,560 - 6s
11s = 260
s = 23.63 miles per hour
Speed of wind = 23.63 miles per hour
Plane speed in still air = 260 miles per hour
C. Action: Divide both sides by 3.
C, 62
Line segment SQ=180, because it is a straight line
90+28=118
180-118=62
hope this helps:)
