See the attached figure to better understand the problem
we know that
in the triangle ABC
tan(alfa/2)=AC/BC----> 5/3
so
(alfa/2)=arctan (5/3)---------> 59.0362°
alfa=2*59.0362--------> alfa=118.07°
alfa+beta=180°----------> because are supplementary angles
beta=180-118.07-------> beta=61.93°
the answer is
the angles are
alfa=118.07°
beta=61.93°
I am really not sure but i think the answer is 29 is there any choices?!?
I found that because i divided 130.50 by 4.5. =)
Hope that helped
Answer:
<u>274.6 inches</u> more snowfall Michigan received during the winter of 1978-79 than in 1930-31.
Step-by-step explanation:
Given:
The state of Michigan recorded an all time high snowfall of 355.9 inches during the winter of 1978-79.
Its lowest snowfall of 81.3 inches was recorded during the winter of 1930-31.
Now, to find how much more snowfall did Michigan received during the winter of 1978-79 than in 1930-31.
The snowfall in 1978-79 = 355.9 inches.
And, the snowfall in 1930-31 = 81.3 inches.
So, to get the how much more snowfall in 1978-79 than 1930-31 we subtract:
Snowfall in 1978-79 - Snowfall in 1930-31.
Therefore, 274.6 inches more snowfall Michigan received during the winter of 1978-79 than in 1930-31.
The value of x is
-4x + 8 = 42
-4x = 42 -8
-4x = 34
x = -8,5
It will be 42 because of the with times the 2nd highest
