Answer:
B. 30
Step-by-step explanation:
The given angles are vertical angles because they are opposite angles created by the same two lines. This means that their value is equal. Let's set up an equation.
85 = 3x - 5
We need to solve for x.
First, combine like terms by adding 5 to both sides.
90 = 3x
Now we want to isolate x by dividing both sides by 3.
x = 30
This is your answer.
Let's check our work by plugging x back into our equation.
85 = 3x - 5
85 = 3(30) - 5
85 = 90 - 5
85 = 85
Your answer is correct.
Hope this helps!
Answer:
Diameter of the circle=21 cm
Radius of the circle=21/2 cm
Circumference of the circle is 2×π×(radius)
Circumference=2×22/7×21/2= <u>66 cm</u>
<u>66 cm</u> is the right answer.
Set them equal together. 4x-8=2x+2. Subtract 2x on both sides. 2x-8=2. Add 8 on both sides. 2x=10. Divide 2 on both sides x=5. Check answer!!!
4(5)-8=12
2(5)+2=12
12=12
So answer is x=5!!!!
