Answer:
see the explanation
Step-by-step explanation:
Let
x ------> the next grade
we know that
To find the average grade sum the grades by the number of math test
so

solve for x
Combine liker terms in the right side

Multiply by 5 both sides

Subtract 372 both sides

-----> this is not make sense
The grade cannot be a negative number
so
For x=0
The minimum average grade is

Answer:
-11/12 make sure you press the negative
Answer:
36°
Step-by-step explanation:
The computation of the measure of the angle is shown below:
As we know that
The trigonometric function in the right angle is
sinα = OS ÷ H
And,
cosα = AS ÷ H
Here
α represent the one of the angles
OS and AS represent the opposite sides
And, H represent the hypotenuse
So
sinx = 8.5 ÷ 14.5
x = arcsin = 8.5 ÷ 14.5
= 35.88
= 36 degrees
