Help on my geometry please ! :(

Step-by-step explanation:

if the measures both the acute angles of a right angled triangle are equal ( 45° ), then the two smaller sides are equal.

so, x = 6

now, by pythagorus theorem :

=》

=》

( because x = 6 )

=》

=》

=》

=======================================================

Explanation:

The value of x = 6 since the two legs of a 45-45-90 triangle are always the same length. This triangle is isosceles.

The hypotenuse of any 45-45-90 triangle is exactly times larger compared to the leg length.

This means,

--------------

We can use the pythagorean theorem to confirm this

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
