The last one as we can see that as the wight increases, the miles per gallon decreases.
Answer:
AC 4x + 16
Angle BEC is 72 degrees
Step-by-step explanation:
AE is 2x + 8, and AC is 2 times bigger, so 4x + 16
Angle EAD is the same as angle EDA, which is 54 degrees, a triangle has 3 sides measuring 180 degrees total, 54 + 54 = 108, so the last angle is 180 - 108 = 72, angle AED is 72, since angle BEC is the same as angle AED, it is also 72 degrees
Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from the given angle, we know the opposite side and want to know the adjacent side. Therefore, we should use the tangent function.
tan(54) = 16/BC
BC = 16/tan(54)
BC = 11.62 units
Hope this helps!
