Answer:
1). x = 14
2). y = 2.4 cm
Step-by-step explanation:
In the diagram ΔNPQ ~ ΔNLM and NL = 3,
1). ∠P ≅ ∠L [All angles of similar triangle are equal in measure]
(3x + 18)° = 60°
3x = 60 - 18
x = 14
2). Since, both the triangles are similar, corresponding sides will be proportional.


y 
y = 2.4 cm
Answer:
- 4x + 4
Step-by-step explanation:
(x-2) × (x-2)
(x × x) + (x × -2) + (-2 × x) + (-2 × -2)
(
) + (-2x) + (-2x) + (4)
- 2x - 2x + 4
- 4x + 4
Given a = 7 and b = 13, this gives us for c:
6 < c < 20, i maybe be wrong
Answer:
11.11%
Step-by-step explanation:
So the question is:
$180 * (x)% = $y
Therefore $180 - $y = $160
Now:
180 - 160 = 20
Therefore; $20 is the discount
Now per cent of discount:
20/180 * 100 = 11.111111111111111111111%
therefore: per cent of discount is 11.11% (rounded to two decimal place)
