First you need to divide 64 by 75 and then multiply by 100 which is 85.3% which then you need to find the average of the 2 which will be (85.3+x)/2=88 where x= the value of the second test.
Then you will need to isolate the x with the following steps:
- multiply each side by 2 making it 85.3+x=176
- Subtract 85.3 from each side
- this results in 90.7

Step-by-step explanation:
Answer: 818.4
Step-by-step explanation:
Using the area of a sector formula, we get the area of the entire sector is 
.
Using the formula 
, we get the area of the triangle is 
.
So, the area of the shaded sector is 
Answer:
2 = 65
1= 115
Step-by-step explanation:
angles 2 and 65° are equal
so input that in for 2
then subtract it by 180°
The lengths of the sides of the triangle:
No sides are equal to each other, so it's a scalene triangle.
Check if the sides satisfy the Pythagorean theorem:
They do, so it's a right triangle.
The triangle is a
right scalene triangle.
