Answer:
d. 15, 30, 135
Step-by-step explanation:
A triangle's interior angles on a flat surface add up to 180 degrees.
a. 90 * 3 = 270 != 180
b.(80 * 2) + 200 = 360 != 180
c.40 + 50 + 60 = 160 != 180
d.15 + 30 + 135 = 45 + 135 = 180, so it has to be d.
(-2,3)(2,6)
slope = (6 - 3) / (2 - (-2) = 3/4....u r absolutely correct :)....
except it is not (-2-2)...it is (2 - (-2)
Let Kiera=x Larry=y Gita=z
x=2y
x=3z
y=(x/2)
x+y+z=8360
x=4560
y=2280
z=1520
Answer:
78
Step-by-step explanation:
x + 21 = 3x - 15
- x - x
21 = 2x - 15
+ 15 + 15
36 = 2x
/ 2 / 2
18 = x
2 (x + 21)
2 (18 + 21)
36 + 42
78
