-213+x=-312
x=-312+213
x=-99
Step-by-step explanation:
if you are solving for X' it is X=4
The equation would be written like this 2x-10=48. First add 10 to both sides so 2x-10+10=48+10 so simplified that is 2x=58. Now, divide both sides by 2 to get x by itself so it will look like this 2x/2=58/2 simplified that is x=29. I hope this helped you.
The required value of Arc BC m = 140° Option B is correct.
Given that,
AD is the diameter of the circle,
∠1 = ∠3 = 20°
Arc BC is to be determined.
<h3>What is an arc?</h3>
Arc is the measure of angle on the circumference of circle.
Here,
∠1 = arc AB
∠3 = arc CD
Now, for circle p
Since angle 1 and angle 2 are equal to the composition of the arc,
Arc AD = Arc AB + Arc BC + Arc CD = 180
20 + Arc BC + 20 = 180
Arc BC = 180 - 40
Arc BC = 140°
Thus, the required value of Arc BC m = 140° Option B is correct.
