One arc is shown as 110 deg.
The arc intersected by the 90-deg angle measure 90 deg.
110 + 90 = 200
360 - 200 = 160
That means the upper arc is 160 deg.
The angle made between a chord and a tangent is half the measure ofthe arc intersected by the chord.
b = 160/2 = 80
Answer: b = 80
Answer:
45.71% I think I'm not sure
Step-by-step explanation:
this equation was tough I dont have an explanation
First, we draw our line.
|------------------------------------------------------------------------------------|
a e
Next, break up this line into segments using the information.
|----------------------|----------------------|--------------------|------------------|
a b c d e
The entire line is 29.
ab + bc + cd + de = ae
ab + bc + cd + de = 29
You also know that
bd = bc + cd
Due to midpoint theorem,
ab = bc
cd = de
Then,
2ab + 2cd = 29
The equations we will use are
bd = bc + cd eq1
2bc + 2cd = 29 eq2
Dividing both sides of the equation in eq2 yields
bc + cd = 14.5
bd = bc + cd
bd = 14.5
