Answer:

BR is about 7.3084 cm

Step-by-step explanation:

the sum of the exterior angles of any polygon is 360. The measure ox x would be 360/15= 24

since I want BR, I will use cos (adj/hyp)

cos24=s/8

.9135=s/8

7.3084=s

Answer:

$x=30^{\circ}$

Step-by-step explanation:

Looking at $\triangle LMN$ :

$\angle NML = 180 - (90+45)$ (angle sum of triangle is $180^{\circ}$ )

$=45^{\circ}$

Looking at $\triangle KNM$ :

$\angle KNM = 180-105$ (angle of straight is $180^{\circ}$ )

$=75^{\circ}$

$\angle KNM + \angle NKM + \angle KMN = 180$ (angle sum of triangle is $180^{\circ$ )

$75+2x+45 = 180$

$2x+120 = 180$

$2x=60$

$x=30^{\circ}$

Hope this helps :)

Stolb23 [73]

At 4200, the max tax is about 2,400 so to get to 3200 raise by 800 which is 1/3
so 1/3 of 4000
or do 16.66 times 3200 which gives u about 53333.33

Answer:

y = 8x - 11

Step-by-step explanation:

Using the equation

y - y1 = m (x - x1)

y - 5 = 8 (x- 2)

y - 5 = 8x - 16

Subtract the 5

y = 8x - 11
