4^2 + 7^2 = c^2

This is because we know that the hypotenuse (c) is always diagonal to the right triangle, so the legs are 4 and 2 (a and b). There is your equation!

Good luck!

How do you work this out
Digiron [165]
Check the picture below.

notice, is just a circle inscribed in a square.

now for the first one, we know the diameter is 14, so the square is a 14x14, and the radius of that is half the diameter or 7.

now, if we get the area of the square, which includes the area of the circle, and THEN get the area of the circle and subtract it from the square's, what's leftover is the shaded section.

\bf \textit{area of a circle}\\\\ A=\pi r^2\\\\
-------------------------------\\\\
\stackrel{\textit{square's area}}{14\cdot 14}~-~\stackrel{\textit{circle's area}}{\pi 7^2}\implies 196-49\pi

now, for the one on the right-hand-side, the radius is 8, and square's area is 16x16,

\bf \stackrel{\textit{square's area}}{16\cdot 16}~-~\stackrel{\textit{circle's area}}{\pi 8^2}\implies 256-64\pi

Divide. Write the answer in simplest form.
Irina-Kira [14]
Turn 2 3/4 to an improper fraction (2*4+3=11/4). Then turn your new improper fraction to the reciprocal (switch the two numbers (4/11). Change the division sign to multiplication (3/16*4/11). Then multiply across (12/176). Then simplify by 4 to get. 3/44.

two triangles are similar. The base of the first triangle is 10 cm and the height is 15 cm. The base of the second triangle is 1
Andrei [34K]

Answer:

the height is 18cm

Explanation:

If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides. Are these ratios equal?

given that

Triangle 1 (first triangle)

base = 10cm

height = 15cm

Triangle 2 (second triangle)

base = 12cm

height = unknown

base 1 / base 2 = height 1 / height 2

10cm / 12cm = 15cm / xcm

xcm = 18cm

height = 18cm
