Answer:
B. 61
Step-by-step explanation:
The sum of arcs around a circle is 360°. This means ...
110° +128° +c° = 360°
c° = 122° . . . . . . . . . . . . . subtract 238°
__
An inscribed angle in a circle has half the measure of the arc it subtends.
a° = 1/2c° = 1/2(122°) = 61°
__
The other angles in the diagram are ...
b° = 1/2(110°) = 55°
d° = 1/2(128°) = 64°
Answer:
-72
Step-by-step explanation:
-32 + (2-6)(10)
PEMDAS
Parenthases first
(-4)(10)
multiply together
(-40)
Then just add the -32 and since a negative plus a negative is always negative the answer is going to be negative
-32 + (-40)
= -72
Answer:
x=4, y=1
Step-by-step explanation:
x + 3y = 7
x - 3y = 1
Add the equations together to eliminate y
x + 3y = 7
x - 3y = 1
---------------------
2x = 8
Divide by 2
2x/2 = 8/2
x = 4
Subtract the two equations to eliminate x
x + 3y = 7
-x + 3y = -1
----------------------
6y = 6
Divide by 6
6y/6 = 6/6
y =1
4x=3y+3 and 6y= 8x+ 36 and y=3x-1 and y= 6- x/3
4x=3y+3 and 6y= 8x are parallel and y=3x-1 and y= 6- x/3 are perpendicular.
See the attached plot for answer.
3/4 would have to be a answer
