Because
and
are alternate exterior angles, this means they <span>congruent or equal to each other.

Therefore, we can say
and use this equation to solve for x.
So x is equal to 12. After finding this, we can now go back to the equation for
and plugin x to solve it.
Therefore,
is equal to 45 degrees.
Angle B= 45 degrees Angle A = 45 degrees A and B are congruent since they are alternate exterior angles 5x-15 = 2x +21 5x = 2x +36 3x=36 X=12 B) 2x12+21 = 45 A) 5x12-15 =45

2x=16mph(fastest bicycle rider)
Answer:
1/6 hours
Step-by-step explanation:
Since it wants a fraction form all you have to do is subract 1/3 from 1/2
1/2 - 1/3
cross multiply:
3/2-2/3
subtract the numerator but multiply the denominator and simplify if you have to:
1/6
The answer is 27.2. (meter is bigger) 1 yard = 91.44 centimeters, and 1 meter= 100 centimeters 91.44 * 120 = 10972.8 100*110 = 11000
(4 sec) * (-10 ft/sec) = -40 ft.
