Answer:
Option (1)
Step-by-step explanation:
Given : m(arc BCD) = 148°
By the property,
Inscribed angle formed by an arc measures half the measure of the arc.
m(arc BCD) = 2(m∠BCD)
148° == 2(m∠BCD)
m(∠BCD) = 74°
Therefore, Option (1) will be the correct option.
Answer:
x = -8
Step-by-step explanation:
Subtract 9 from each side
-x = 8
Divide each side by -1 to get rid of the negative in x
x = -8
Answer:
6
Step-by-step explanation:
In equilateral triangle, all the sides are congruent.
3x - 6 = 12
Add 6 to both sides
3x = 12 + 6
3x = 18
Divide both sides by 3
x = 18/3
x = 6
