Answer:
a. x = 180 - (j + k)
b.
j + k = (5x - 2) + (2x - 2) = 7x - 4
l = x
x = 180 - (7x - 4)
x = 180 - 7x + 4
8x = 184
x = 184/8
x = 23
l = 23°
j = 5x - 2
j = 5 × 23 - 2
j = 115 - 2
j = 113°
k = 2x - 2
k = 2 × 23 - 2
k = 46 - 2
k = 44°
<em>or k = 180 - (23 + 113) = 180 - 136 = 44°</em>
Answer: 42
Step-by-step explanation:
To solve this question, we have to find the lowest common multiple of 9, 12 and 18 and then add 6. This will be:
Multiple of 9 = 9, 18, 27, 36, 45
Multiple of 12 = 12, 24, 36, 48, 60
Multiple of 18 = 18, 36, 54, 72, 90
The lowest common multiple is 36. Ww will then add 6. This will be:
= 36 + 6
= 42
To solve for the interior angles for a polygon,
subtract 2 from the number of sides then multiply with 180
i.e, (n-2)180
e.g, in the case of a triangle, (3-2)180 = 1*180 = 180
As for square, (4-2)180 = 2*180 = 360
