Answer:
(a) 17°
(b) 78°
Step-by-step explanation:
(a) sin A= 0.2896
to calculate for "A" check for sin inverse of 0.2896
A= sin^-1(0.2896) = 16.83
to the nearest degree A= 17°
(b) tan A = 4.7046
A= tan^-1(4.7046)
A = 77.99
to the nearest degree A = 78°
Answer:
c
Step-by-step explanation:
The set of real numbers is all numbers that can be shown on a number line. It also includes rational numbers, which are numbers that can be written as a ratio of two integers, and irrational numbers, which cannot be written as a the ratio of two integers.
Answer:

Step-by-step explanation:
The submersible is diving at a down angle of 15° along the hypotenuse AC of triangle ABC.
Its horizontal track along the surface AB is 1500 ft.

The submersible was already at a depth of 250 feet when it began the dive.
New depth = 250 + 402 = 652 ft

so sixteen times 2 is 32 +1 is 33 so yi is 32 I think I'm not sure cause I dont get that
