A) 90

1 answer:

6 0

We know that AB is perpendicular to CD. (that was given)

Perpendicular angles are 90 degrees because two straight lines (180) crossed make 4 90 degree angles.

180+180=360

90*4=360 See the similarities?

7x+6= 90 degrees

Subtract 6 on both sides.

7x=84

Divide both sides by 7.

x=12

"B" is the correct answer.

I hope this helps!

maria [59]

Answer:

It can cover 203 km with 14 litres.

Step-by-step explanation:

Given that,

A car can cover a distance of 522km on 36litres of diesel.

522 km = 36 litres

1 l = (522/36) km

We need to find how far can it travel with 14 litres.

We can use the unitary method to solve it.

$14\ L=\dfrac{522}{36}\times 14\\\\=203\ km$

So, it can cover 203 km with 14 litres.
