Answer:

We know that since it's a square, the lenght size is the same on all sides. We can simply use pythagoras theorem:

a^2 + a^2 = 13.5^2

13.5^2 = 182,25‬

182,25 : 2 (because there are 2 'a') = 91,125

The square root of 91,125 is 9,55 feet.

Can someone plz help me

Vanyuwa [196]

Answer:

Step-by-step explanation:

Notice how the angles look the same, but if we look at the base of our second house, it's value is triple that of the first house. Therefore, we can infer that the other values must be triple the size, as well. Thus, multiplying our values of the first house, we get answer C!

Hope this helped!

This is one of the things I need help on?

Answer:

Here's your solution

=> Both angles are interior angles hence their

=> sum will equal to 180°

 => (2x + 10)° + ( x + 5) = 180°

=> 2x + 10° + x + 5° = 180°

=>.3x + 15° = 180°

=> 3x = 180° - 15°

=>. 3x = 165°

=>. x = 165/3

=>. x = 55°

=> hence angle = 120° and 60°

hope it helps

When a>0 and c is a positive integer, the expression (4a)^c/3 is equivalent to

Marat540 [252]

Answer:

Step-by-step explanation:

a is greater than 0 and is inside the root of the equation

when a fraction is a power the bottom number of the fraction becomes the nth root and the top number becomes what the number is powered by

in this case the bottom number is 3 so the three goes on the place where the nth root goes

it is to the c power so c is on the outside
