D. 68
I don’t remember what formula this is called but the formula says that all angles in a triangle should add up to 180, so 75+37= 112, 180-112= 68
Answer:
r1 is given by the formula an=a1r.n-1
Step-by-step explanation:
Answer:
3 or D
Step-by-step explaintain
Your problem statement tells you
f(x) passes through point (3, negative 1)
g(x) passes through point (3, negative 1)
This tells you the input value that produces the same output value for the two functions is 3, and that output value is -1.
Answer:
D. cosine
Step-by-step explanation:
As it can be seen in the figure, the triangle ABC is a right-angled triangle with Angle C = 90 degree.
In a right angle triangle, there is a formula as following:
<em>cosine (of an acute angle) = length of adjacent side/ length of hypotenuse</em>
In the figure, the point of angle B and length of hypotenuse AB are given.
We have to calculate x - length of the given side. As BC is the adjacent side of angle B
=> we can use the above formula to calculate x
So that we can use cosine
Answer:
5/4×9/10
<u>5*9</u> = <u>45</u> <u>(divide by least common denominator)</u> = <u>9</u>
4*10 40 (divide by least common denominator) 8
Step-by-step explanation:
The least common denominator is 5
