Step-by-step explanation:
- put your finger on zero and move it to -1 then go up to positive 1 and put ur dot there.
- put ur finger on 0 again then go to -1 but now u move down to -2 and put ur dot there.
- now put ur finger on the zero and go to the opposite side to positive 2 then go down to -2 and put ur dot there. Hope that helps :)
Answer:
Step-by-step explanation:
Parallel lines are lines that never meet, from the question in the attachment above, the two lines that cannot meet are lines 'a' and 'b' and lines 'c' and 'd'
4. Question four is then lines b and a which is option B
Perpendicular lines are lines in which the angle between them is right angle (90 degrees). Which are 'a' and 'c', 'a' and 'd', 'b' and 'c', 'b' and 'd'
5. Question 5 is therefore 'a' and 'c' which is option D
Answer:
D) 134°
Step-by-step explanation:
i took the test
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
