Answer:

x=5

AOB = 8

BOC = 13

AOC = 21

Step-by-step explanation:

<em>Angle AOB and Angle BOC is equal to Angle AOC.</em>

AOB = x+3

BOC = 4x-7

AOC= 2x+11

AOB + BOC = AOC

x+3+4x-7 = 2x+11

5x-4 = 2x+11

3x = 15

x = 5

Therefore, the value of x is 5.

<em>Angle AOB = x+3</em>

AOB = 5+3

AOB = 8

<em>Angle BOC = 4x-7</em>

BOC = 4(5)-7

BOC = 13

<em>Angle AOC = 2x+11</em>

AOC = 2(5)+11

AOC = 21

Answer:

x=5

\angle AOC=21

\angle AOB=8

\angle BOC=13

Step-by-step explanation:

We are given that

\angle AOB=x+3

\angle AOC=2x+11

\angle BOC=4x-7

We have to solve for x and find the angle measures

\angle AOC=\angle AOB+\angle BOC

2x+11=x+3+4x-7

2x+11=5x-4

11+4=5x-2x

15=3x

x=\frac{15}{3}=5

Substitute the value of x then, we get

\angle AOC=2(5)+11=21

\angle AOB=5+3=8

\angle BOC=4(5)-7=13

To start, we're given the range that x lies in: from -1 to 4. We know from the fact that -1 \leq x that -1 will be <em /><em>included</em> in that range, so we mark -1 on the number line with a solid circle. We also know from x\ \textless \ 4 that, while x can be any value <em>up to</em> 4, it does not <em>include </em>4. We indicate this by drawing a hollow circle around 4 on the number line. Since x can be <em>any value within this range</em>, we make that fact clear by drawing a bold line between the points -1 and 4 on the number line. I've attached an image of what our final graph would look like.

What is the area of the figure? Use 3.14 for π. Round to the nearest hundredth if necessary.
vfiekz [6]

Answer:

81.12 cm²

Step-by-step explanation:

The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.

(3.14 * 4²)/2 + (14 * 8)/2 <em>(Work the operations in parentheses first.)</em>

(3.14 * 16)/2 + 112/2

50.24/2 + 112/2 (<em>Divide 50.24 by 2. Do the same for 112.)</em>

25.12 + 56 (<em>Add 25.12 & 56.)</em>

81.12 cm²

The area of the figure is 81.12 cm².
