Answer:
x = 60°
Step-by-step explanation:
This is a congruent triangle, and the extension is parallel to one side, also making it 60°. All congruent triangles are equilateral.
Hope this helps! :-)
Answer:
They are 53, 55, 57, 59 and 61.
Step-by-step explanation:
We can write the integers as x, x+2, x+4, x+6 and x+8, so
x + x + 2 + x + 4 + x + 6 + x + 8 = 285
5x + 20 = 285
5x = 265
x = 53.
Answer:
Add 1 and 6, then divide by 2 and multiply by 3.
Step-by-step explanation:
Common ratio = -20/8 = -2.5 Answer
Next 3 terms are 50*-2.5 , 60*(-2.5)^2 and 50 * (-2.5)^3
= -125, 312.5 and -781.25 Answer
Answer:
y=-3x+6
Step-by-step explanation:
(y2-y1)/(x2-x1)
(0-6) / (2-0)
0-6= -6
2-0= 2
-6/2= -3
slope is -3
so now we have y=-3x+b
in the coordinates (0,6) it means if x is 0 then y is 6. so the y-intercept is 6.
Therefore the equation would be y=-3x+6
