Answer:
x= 50°
Hope it helps!
Step-by-step explanation:
The sum of the exterior angles of a polygon is always 360°
So, x+40+x+20+2x+2x = 360
6x + 60= 360
6x = 360-60 = 300
6x= 300
x= 300/6
= 50
Answer: red 36 m
Step-by-step explanation: base plus base = 18 / 2 = 9 * 4 = 36 m
Answer:
aₙ=(-2)ⁿ*2.
Step-by-step explanation:
1) -4*(-2)=8; 8*(-2)=-16; -16*(-2)=32, ...
2) the required equation is:
aₙ=(-1)ⁿ*2ⁿ*2; ⇒ aₙ=(-2)ⁿ*2 or aₙ=(-1)ⁿ*2ⁿ⁺¹.
The slope is the number next to the variable and the y intercept is the number after the slope.
#1. Slope= -3
Y-intercept=-3
#2. Slope=5/2
Y-intercept=-4
#3. Slope=1/3
Y-intercept=3
#4. Slope=-2
Y-intercept=2
#5. Slope=-2/5
Y-intercept=-2
#6. Slope=-2/3
Y-intercept=-2
C = 2πr Divide both sides by 2r
= π Switch the sides to make it easier to read
