Answer: B
Step-by-step explanation: Since all triangles have angles that add to 180 degrees, add the two known angles and then subtract that from 180.
29 + 108 = 137
180 - 137 = 43
Answer:
-7
Step-by-step explanation:
y=3x-7
x=0 ⇒ y= 3*0-7= -7

Answer: The width of the rectangle is 10.2 inches, the perimeter is 71.4 inches, the area is 260.1 inches.
Step-by-step explanation:
25.5/5=5.1
5.1*2=10.2
The width is 10.2 inches
25.5*2+10.2*2=71.4
The perimeter is 71.4 inches
20.5*10.2=260.1
The area is 260.1

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Set up equation.</em>
mAB + mBC = mAC
x + 4 + 4 = 3x + 2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: x + 8 = 3x + 2
- Isolate <em>x</em> terms: 8 = 2x + 2
- Isolate <em>x </em>term: 6 = 2x
- Isolate <em>x</em>: 3 = x
- Rewrite: x = 3
<u>Step 3: Find AB</u>
- Define: mAB = x + 4
- Substitute in <em>x</em>: mAB = 3 + 4
- Add: mAB = 7
