Answer:
19. 21.12, 15. 30 degrees
Step-by-step explanation:
Given: angle theta is equal to 75 degrees
Length of the string is equal to 20m.
Find: the height of the kite from the ground
Solution:
sin 75^0 = h/ 20
0.9659 = h/20 applying the law of proportion
h = 0.9659(20)
h = 19.32
The height of the kite is the value of h plus the height of Rico
= 19.32 + 1.8
= 21.12 -- answer
15. Sin x = 15/30, where x is the unknown angle
= 0.5
take the arcsine of 0.5
Angle x = 30 degrees
