Answer:
3
Step-by-step explanation:
y=-1/3x-6, for this line, the slope (m) is -1/3.
This is because the equation is in the slope intercept form: y = mx + b.
The perpendicular line to one with m = -1/3, is the negative reciprocal of m, we'll call it m2.
m2 = --3/1 = +3/1 = 3
Answer:
B 6.3
Step-by-step explanation:
r = 8
l = 2*3.14*r
l = 50.24
s=l/360*45
s≈6.3
Depends on the shape of the region. Need more information.
Answer:
x=15 degree
Step-by-step explanation:
5x +5+6x -1+3x+5x+3+4x+8 =360 degree (exterior angles of pentagon is 360 degree)
23x +15 =360
23x=360-15
x=345
x=345/23
x=15 degree
