Answer:
x = 8
Step-by-step explanation:
∠VUD + ∠WUV = 180° {Straight line}
86 + ∠WUV = 180
∠WUV = 180 - 86
∠WUV = 94°
Sum of all angles of triangle = 180°
∠VUW + ∠UWV + ∠WVU = 180
94 + x + 8 + 9x - 2 = 180
10x + 100 = 180
10x = 180 - 100
10x = 80
x = 80/10
x = 8
Answer:
The answers are in the question.
Step-by-step explanation:
The wording can be off-putting but the answers are mostly there for you. It says that when the wind was at the tail of the plane, the travel was hastened to 5 hours instead of six. Is the rate of speed with the wind in favor of the plane is r+21, then it stands to reason that traveling AGAINST the wind will cause the rate to drop to r-21. Taking the average of the two travel times (5 and 6 hours each), we get 5.5 hours. Since speed is distance divided by time, the speed of the plane in still air will be <em>d</em> / 5.5
Be sure to label the speed as mph.
Answer:
Rational
Step-by-step explanation:
The meaning of vertical angles are two congruent angles formed by the intersection of two straight lines.
On this question is given that angles one and two are vertical, and the measure of one of them or angle two is 31 degrees.
As said before vertical angles are congruent, or have the same measurement.
Meaning that angle one is equal to 31 degrees.
I think it is a glide reflection.
