So, we know that the internal angles of a triangle add up to 180 degrees, yes?
60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.
Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!
Hope I helped!! :)
Answer:
A. 30 degrees
Step-by-step explanation:
side by side angles on a flat line have to equal 180 degrees. if angle 5 = 150 degrees, 180 - 150 = 30 degrees.
To find the percent increase, you will first find the difference in price for the peak season economy and the regular economy price.
$526.3-$440.8=$85.50
Then divide the difference by the beginning price(economy).
85.50/440.8= 0.19
The percent increase is approximately 19%.
