Based on the figure, select all true equations. Angle A is 48 degrees
Angle C is 90 Degrees

A. Angle B is 42 degrees
B. Side a is the hypotenuse
C. sin A = a/c
D. tan B =b/a
E. cos B = a/c
F. This is not a right triangle, so right triangle trigonometry does not apply

E

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

central angle of a triangle has the same measure as its intercepted arc.
