Q5.

x it's a diagonal of a square.

The formula of a length of diagonal of a square:

a - side of a square

We have a = 45.

Substitute:

Q6.

Look at the first picture.

In a triangle 45° - 45° - 90°, all sides are in ratio 1 : 1 : √2.

In a triangle 30° - 60° - 90°, all sidea are in ratio 1 : √3 : 2.

Look at the second picture.

from the triangle 45° - 45° - 90°

       multiply both sides by √√2  (use √a · √a = a)

     divide both sides by 2

from the triangle 30° - 60° - 90°

Step-by-step explanation:

30°-60°-90° Triangles

Hypotenuse → 2x

Short Leg → x

Long Leg → x√3

45°-45°-90° Triangles

Hypotenuse → x√2

Two identical legs → x

6. You solve the shorter triangle first:

Now that we know our x-value, we can solve the larger triangle:

5. This exercise is EXTREMELY SIMPLE since two congruent isosceles right triangles form that square, so all you have to do, according to the rules for 45°-45°-90° triangles, is attach to 45, giving you
