Answer:

80 degrees

Step-by-step explanation:

We can use the Central Angle Theorum, which states that if the vertex of the angle is the center of the circle, then the arc is the same measurement as the angle.

In this case, m<COB is 80 degrees, and the vertex is the center of the circle, which means that measure of arc CB is also 80 degrees

Question # 5 what is the sum?​
Blizzard [7]
Answer: C) d+13/d+4

Here’s why:

Step 1: Rewrite the factor
d^2 + 7d +4d +28 / (d+4)^2 + 6 / d+4

Step 2 : factor out d from the expression and factor out 4 from the expression
d × (d+7) + 4(d+7) / (d+4) ^2 + 6 / d+4

Step 3: Factor out d+7 from the expression
(d+7) × (d+4) / (d+4) ^2 + 6 / d+4

Step 4: simply the expression
d+7 / d+4 + 6/ d+4

Step 5: write all numerators above the common denominator
d+7+6 / d+4

Step 6: add the numbers and you get
d+13 / d+4

Fill in the space to make the equation true 3y5*__y—=12y2
serg [7]

Answer:

The second blank, which is the exponent on the y there, is -3.

3y^5 \cdot 4y^{-3}

Step-by-step explanation:

3(?)=12 implies ?=4 since 3(4)=12.

y^5 \cdot y^{?}=y^{5+?}=y^{2} implies 5+?=2.

5+?=2 can be solved by subtracting 5 on both sides. This gives you:

?=2-5

?=-3

Let's put it altogether:

3y^5 \cdot 4y^{-3}

12y^{5+(-3)}

12y^{2}

So the first blank is 4.

The second blank, which is the exponent on the y there, is -3.
