Answer:
a=6.9
Step-by-step explanation:
Since you know that C is a right angle, you can use the Law of Sines to find a. The first step is to find the size of the angle A, which is 180-74-90=16. Now, you set up a ratio that involves 3 knowns and one unknown to get 
, which after cross multiplying yields 
. PM me if you have any questions?
B)57 is the answer for your question
Answer:
v= 2.66 m/sec
Step-by-step explanation:
supposing we have to find their speed just as he grabs her.
Applying law of conservation of Energy
That is
p_i= p_f
Initial momentum = p_i = 35×0+ 44×4.9= 210.6 kg.m/sec.
final momentum p_f= (35+44)v
let the final velocity of combined body be v
therefore,
79v= 210.6
v= 2.66 m/sec.
