Step-by-step explanation:
2(X-1)=16
2X-2=16
2X=16+2
X=18÷2
X=9
I don't understand (3×1)-(5=86)-10
I think it is wrong or sth I don't know!
X multiplied by two plus six
Answer:
Step-by-step explanation:
11/77=x/21
x=3
All of the angles add up to 360 degrees.
180(4-2) = 360
9x+1+5x-12+8x+61
Add up all the like terms
22x+50= 360
x=14.1
We are going to add up all of the angles together and subtract them by 360 in order to find the measurement of the missing angle.
Angle C: 9(14.1) + 1 = 127.9
Angle D: 5(14.1) - 12 = 58.5
Angle A: 8(14.1) + 61 = 173.8
All of these angles add up to 360
This means that angle D is 0 degrees since all of the other angles already add up to 360.
<u>Answer</u>
0 degrees
(-6,26) are the coordinates of the other endpoint because it it the same distance from the midpoint in the opposite direction of the other endpoint
