Answer:
52,5°
Step-by-step explanation:
0,5 × (135 - 30)
= 0,5 × (105)
= 52,5°
Answer:
y=1/2x+2(2 is the y-intercept)
The blue line and black line have the same y-intercept, but the black line has a slope 1/6 greater than the blue line.
Hope it helps <3
Step-by-step explanation:
12. Cos 60° = 8/c
0,5 = 8/c
0,5 c = 8
c = 16
D² = V16²-8²
= V256-64
=V192 = V16×12 = 4V12
= 4V4×3 = 8V3
13. Cos 30° = 6/b
V3/2 = 6/b
V3 b = 12
b = 12/V3
b/Sin B = a /sin A
b/Sin90° = 6/ sin 60°
<u>b</u> = <u> </u><u> </u><u> </u><u>6</u><u> </u><u> </u><u> </u>
1 V3/2
b× <u>V3</u> = 6
2
b = 6× 2/V3
= 12/V3
So you divide 50 by 2 so there are 25 before him
Answer:
The equation would be y=2x+3 I am pretty sure
Step-by-step explanation:
This is because you take the slope which is 2 from the line y=-1/2x-6. To find the slope perpendicular to the line, you need to find the exact opposite of the slope: -1/2, and in this case, it would be 2.
(Ex: if it was -3/4, you would need to use a slope of 4/3 since it is the opposite)
Then you take that slope (2) and the point (0, 3) and put it into "y-y1=m(x-x1)"
y-y1=m(x-x1)
y-3=2(x-0)
-distribute the 2-
y-3=2x-0
-add 3 on both sides-
so equation would be y=2x+3
Not sure if this is all correct, but I hope it helps! :)
