Step-by-step explanation:
Answer:
Pizza: 27°
Curry: 108°
Fish and Chips: 63°
Kabab: 27°
Other: 135°
Step-by-step explanation:
Frequency 40 = 360°
Pizza (3) =
* 360° = 27°
Curry (12) =
* 360° = 108°
Fish and Chips (7) =
* 360° = 63°
Kabab (3) =
* 360° = 27°
Other (15) =
* 360° = 135°
27 + 108 + 63 + 27 + 135 = 360
An outside angle equals the sum of the two opposite inside angles.
So you have:
(5x-35) = 2x +58
Solve for X then you can calculate Angle B:
(5x-35) = 2x +58
Subtract 2x from both sides:
3x -35 = 58
Add 35 to both sides:
3x = 93
Divide both sides by 3:
X = 93 /3
x = 31
Now for Angle B, replace x with 31:
Angle B = 2x = 2(31) = 62 degrees.
The answer will be 8.555555555555555556 (it's a repeating decimal)
