Step-by-step explanation:
The question is incomplete, as the sector, its area and the angle at the center are not given.
I will solve this using the following illusration
The area of a sector is:
Assume that:
The equation becomes
Simplify
Take:
Cross Multiply
Solve for
Take square roots
Answer:
C. n=4 or n=-4
Step-by-step explanation:
10lnl-3=37 original problem
+3=+3 add 3 to both sides
10lnl=40 solve that portion
<u>10lnl=40</u>
10 divide both sides by 10 to isolate the variable
lnl=4 since n is an absolute value, it is the distance from zero making the solution 4 or -4.
For option d:
5x - 7y = 10 . . . . . (1)
10x - 14y = 8 . . . . (2)
(1) x 2 => 10x - 14y = 20 . . . . . (3)
(2) - (3) => 0 = -14 [not possible]
Therefore, the set of equations in option d, has no solutions.
Answer:
x = 6
x = -2

Hey There!!
By looking at the diagram:
m3 = 180-m4
sum of the angles = m1 + m2 + m3 = 180 degrees
substituting the value of m3:
m1 + m2 + ( 180 - m4 ) = 180
m4= 180 - m3
m1 + m2 + (180 - m4) - (180-m4) = 180 - (180-m4)
Hence:
m1 + m2 = m4
so the right answers after concluding from the above calculations is:
A. m1 + m2 = m4
C.m4 is greater than m2
D. m4 is greater than m1
