Answer:
11.8845
Step-by-step explanation:
11.8845 to the up and down answer it will be down
The given angles are complementary, therefore:
(5r + 5) + (8r -6) = 90°
13r - 1 = 90
13r - 1 + 1 = 90 + 1
13r = 91
13r/13 = 91/13
r = 7
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:
4.11 (rounded to the hundredth place, the actual answer is 4.1(with the one repeating))
Step-by-step explanation:
To solve 37 divided by 9 you have to do long division or you can use a handheld calculator.
To solve it through long division,
9 can go into 3 zero times
9 can go into 37 four times though
9*4 is 36
So subtract 36 from 37, leaving 1.
9 can go into 1 zero times.
Add a zero behind the one and 9 can go into 10 once.
The pattern continues forever, making the answer 4.1(with the one repeating)
or 4.11 (rounded to the hundredth place)
