Question

Solve for c I need answers bad please

Answer 1

Answer:

c = sqroot45

Put a 45 in the box under the square root.

Step-by-step explanation:

Use Pythagorean Theorem. See image.

Also, sqroot45 can be simplified. It 3root5, just in case they ask that next.

Answer 2

Answer:

c=√45

Step-by-step explanation:

I'm assuming this question is before Pythagorean theorem so.

1. Find the total area of the big square.
2. Find the total area of the four right-angled triangles.
3. Subtract the big square with the four right-angled triangles to find the area of the smaller square with sides 'c'.
4. Lastly, square root (√) the value to find c. Because c²=area of smaller square.

Big square area:

$(3 + 6) \times (3 + 6) = 81$

All four right-angled triangles area:

$4( \frac{1}{2} \times 3 \times 6) = 36$

Smaller square area:

$81 - 36 = 45$

Value of c:

${c}^{2} = 45 \\ c = \sqrt{45}$
