Since the lines u and v are parallel, this means that the angles (10x - 5) = (7x + 4)
and that 7x + 4 + y = 180.

You can solve the first equation for x, then substitute that value into the second equation and rearrange for y.

10x - 5 = 7x +4
3x -5 = 4
3x = 9
x = 3°

∴ 7(3) + 4 + y = 180
25 + y = 180
∴ y = 180 - 25
y = 155°

<h2>Option B:</h2><h3>112 families </h3>

Step-by-step explanation:

Given,

No. of families = 75

Out of 75 no. of families had cars = 42

Out of 1, no. of families can have cars

$= \frac{42}{75}$

Therefore, 

Out of 200 families, no. of families had cars

$= 200 \times \frac{42}{75}$

$=200 \times \frac{14}{25}$

= 8 × 14

= 112

Hence, 

option B is correct as 112 families have cars out of 200 families (Ans)

What is special about a 30 60 90 triangle?

Nata [24]

A 30-60-90 triangle is special because of the relationship of its sides. Also It turns out that in a 30-60-90 triangle, you can find the measure of any of the three sides, simply by knowing the measure of at least one side in the triangle.

Hope this helps. :)
