<h3>What is angle bisector?</h3>
Angle bisector in geometry refers to a line that splits an angle into two equal angles. Bisector means the thing that bisects a shape or an object into two equal parts.
Given:
AT bisects <MAR
and, m<MAT= (6x-4) and and m<RAT = (2x+8)
As, <MAR is bisected by ray AT.
So,
<MAT = <RAT
6x-4= 2x+8
6x- 2x = 8+4
4x = 12
x= 3
So, <MAT = 6x-4= 6*3-4= 14
and, <RAT = 2x+8 = 14
Hence, MAR= <MAT + <RAT = 14+14=28

Answer:
C
Step-by-step explanation:
10.56/ 96= 0.11 which you can round down to 0.10
Answer:
4 ; 32
Step-by-step explanation:
Given that :
Number of observations, n = 9
Let observations = X
ΣX = 360
The mean, (m) is calculated using the formula :
m = ΣX / n
m = 360 / 9
m = 4
Σ(X - m) = 288 (sum of square of deviation )
Variance is calculated using the formula :
[Σ(X - m) / n]
Variance = Sqrt(288 / 9)
Variance = 32
The length of the major arc QSR is 39.77 inches
<h3>How to find the length of the major arc QSR?</h3>
The given parameters are:
m∠QPR = 170 degree
Radius, r = 6 inches
The length of the major arc QSR is calculated as:
Arc length = (360 - Angle/360) * 2πr
Substitute the known values in the above equation
Arc length = (360 - 170/360) * 2 * 3.14 * 6
Evaluate the difference
Arc length = (190/180) * 2 * 3.14 * 6
Evaluate the product
Arc length = 39.77
Hence, the length of the major arc QSR is 39.77 inches

-20/(-2)
when you divide two negative numbers, the answer becomes positive:
-20/-2 = 10
10 is your answer
Note for multiplying and dividing:
two positive numbers will give you a positive answer
one negative numbers and one positive number will give you a negative answer
two negative numbers will give you a positive answer
