A)
Because the sum of angles in a triangle must equal 180° we can say:
62+α+90=180
α+152=180
α=28°
b)
Since all sides have equal length, all angles must have equal measure. (This is an equilateral triangle). And again, because the sum of the angle must be 180° we can say:
b+b+b=180
3b=180
b=60°
(-5/3)•(-6/1)=(30/3)
(30/3) simplified is (10/1)
Answer:
1 ) y = 2x - 1
slope = 2
y intercept is (0,-1)
2) y = -1/2x + 5
slope = -0.5
y intercept = (0,5)
Step-by-step explanation:
All you do is divide -12/20 by 4/4 which is -3/5
I believe it is $0.50.
$2 divided by 4 equals $0.50.
