Answer:
Step-by-step explanation:add by 13
12 + 13 = 25
25+ 13= 38
Given
two angles (150° and 12°) and the shortest side (12 cm) of a triangle
Find
the second-shortest side
Solution
Strategy: Make use of the Law of Sines to find missing side lengths when angles are known. To find the third angle, make use of the sum of angles of a triangle.
The sum of angles of a triangle is 180°, so we have
... 150° + 12° + C = 180°
... C = 180° - 162° = 18°
The law of sines tells us
... c/sin(C) = b/sin(B)
... c = sin(C)·b/sin(B) = sin(18°)·(10 cm)/sin(12°)
... c ≈ 14.9 cm
_____
We are calling the sides a, b, c. We are calling the angles opposite those sides A, B, and C.

Answer:
D. $53
Step-by-step explanation:
Given the function, f(x) = 10x + 8, representing how much Jack earns working for x hours, if Jack works from 2:30 P.M to 7:00 PM, it means Jack worked for 4 hours 30 minutes, which is 4.5 hours (30 minutes = 0.5 hr).
Therefore, to find out how much he earned working for 4.5 hours, substitute x = 4.5 in
✅Jack will earn $53 for working between 2:30 PM and 7:00 PM
