Answer:
Step-by-step explanation:
For angle C,
cos(∠C) = 
= 0.97
sin(∠C) = 
= 0.26
tan(∠C) = 
= 0.27
Therefore, from the triangle ABC,
cos(∠A) = cos(90° - ∠C)
= sin(∠C)
= 0.26
sin(∠A) = sin(90 - ∠A)
= cos(∠A)
= 0.97
tan(∠A) = 
= 3.73
Angle 
A 0.26 0.97 3.73
79.57 times 12% = 70.02
70.02 times 7.75% = 5.43
70.02 plus 5.43 = 75.43

Answer:
a = 6.25 m/s²
T = 5⅓ seconds
Step-by-step explanation:
a = (v - u)/t
v = 120×1000/3600 = 100/3
a = 100/3t
v² = u² + 2as
(100/3)² = 2(100/3t)(88 8/9)
10000/9 = (200/3t)(800/9)
200/3t = 12.5
t = 5⅓ seconds
a = 6.25
28+22+29+ 21 (your answer) = 100 divided by 4 (the amount of numbers used) = 25 (average)
