Answer:
you have it right, its 60. since all sides are equal, then all angles must be equal. triangles are 180, so 180 divided by 3= 60
Step-by-step explanation:
The answer would be d.) An=An+1-4.3
20x + 15y = 2000
x + y = 115
55+60=115
20 (55) + 15 (60)=2000
1100+900=2000
2000=2000
Answer:
(a) The y-intercept is not visible on the graph.
(D) The line crosses the x-axis at –3
Step-by-step explanation:
i already did this on edge
17. Area of triangle: 1/2bh
1/2 * 12 * 15
1/2 * 180
=90 cm^2
18. Area of trapezoid: 1/2 h (b1 + b2)
1/2 * 8 ( 12 + 15.4)
4 * 27.4
= 109.6 cm^2
