Answer:
cosA = 0.6
Step-by-step explanation:
Using the Pythagorean identity
sin²A + cos²A = 1 ( subtract sin²A from both sides )
cos²A = 1 - sin²A ( take the square root of both sides )
cosA = ± 
Since only the positive value is required , then
cosA = 
= 
= 
= 0.6
Answer:
then call 911
Also the answer would be B. i think
Step-by-step explanation:

Then recall that the integral of 
is
(or you can find that out by integrating by parts) and so
Answer:
Step-by-step explanation:
∠A=∠B
4X+7=5X-3
X=7+3=10
5*10-3=50-3=47
