Z=kX
When x=6, z=18,
Finding value of z,
18=k*6
k=3
Z=3X
when x=10,
Z=3*10
Z=30
Part B;

Triangle Have 180°
- 180 - 90 = 90
- 90 × 2 = 180
Half of triangle Have 90°
Answer:
Alix does. See below.
Step-by-step explanation:
Givens
<em><u>Jenny</u></em>
- b1 = 90 cm
- b2 = 80 cm
- height = 23 cm
<em><u>Alex</u></em>
- b1 = 90 cm
- b2 = 70 cm
- height = 27 cm
Formula
For both territories the answer is based on the formula
Solution
<em><u>Jenny</u></em>
- Area = (90 + 80)23/2
- Area = 170 * 23 / 2
- Area = 85 * 23
- Area = 1955 units.
<em><u>Alex</u></em>
- Area = (70 + 90)*27/2
- Area = 160*27 / 2
- Area = 80* 27
- Area = 2160

Parallel lines have the same slope. So if a line has a slope of 2, a line parallel to it also has a slope of 2.
