Answer:
153.86
Step-by-step explanation:
To find the area of a circle, we use the formula .
d=14
r=d/2
r=7
153.86
So I took the test and my teacher said to label all of the degrees so
angle 1,3,5,7,9,11,13,15 all = 95 degrees
angle 2,4,6,8,10,12,14,16 all = 85 degrees
I know 1 and 3 are vertical angles
3 and 8 are same side interior angle
4 and 14 alternate interior angles
6 and 12 are alternate exterior angles
13 and 9 are corresponding angles
4 and 7 are same side interior angles
I believe these are correct but you might want to double check with some other source
Answer:
2
Step-by-step explanation:
Since 12/15 is equivalent to 4/5.
4/5 is equal to 8/10 so that would mean 8/3 = 2 remainder 2
Answer:
38
Step-by-step explanation:
We are given 2 points with there coordinates easy to calculate:
the upper one A(1,15) & the lower one B(6,10). Moreover the equation of this linear function is y = mx + b
1st) calculate m= (10-15) / (6-1) [FOMULA m=(y₂ - y₁) / (x₂ - x₁)]
m= -5/5 ==> m= - 1==> y=-x + b. To calculate b, replace x & y by any of the 2 points A, B. Say A(1,15)
15 = - (1) + b ==> b= 16 & final equation y = -x +16
