Answer:
A = 38°
Step-by-step explanation:
We are going to use cosine law to find angle A where
a = 4.7
b = 3.9 m
c = 2.9 m

or

cos A = [(4.7)^2 + (3.9)^2 - (2.9)^2]/2(4.7)(3.9)
= 28.89/36.66
= 0.788
A = arccos(0.788) = 38°
Answer:
The words are blurry I can't view it.
Step-by-step explanation:
24365x = 16820
x = 16820/24365
x(rounded to the nearest tenth) = 0.70
Answer:
y=2
x=5
trust me its by calculator
