Answer:
m∠b = 35°
m∠c = 145°
m∠ d = 35°
Step-by-step explanation:
To find m∠b, we use Definition of Supplementary Angles:
180 - (90 + 55) = 35°
To find m∠c, we also use Definition of Supplementary Angles:
180 - 35 = 145°
To find m∠d, we use Vertical Angles Theorem:
m∠b = m∠d = 35°
Hello!
Let's write this as an equation below.
3/4x=87
To find our answer ,we just divide both sides of the equation by 3/4.
x=116
Therefore, 116 people attended the concert.

Answer:
Option B
Step-by-step explanation:
Formula to be used to calculate the length of an arc,
Length of arc = 
Here, θ = Angle subtended at the center by the arc
r = radius of the circle
By substituting values in the formula,
s = 
Therefore, Option B will be the answer.
