The legs are 5 inches long.

Use the Pythagorean theorem:
5^2+5^2=c^2 \\
25+25=c^2 \\
50=c^2 \\
c=\sqrt{50} \\
c=\sqrt{25 \times 2} \\
c=5 \sqrt{2} \\
c \approx 7

The length of the hypotenuse of the triangle is approximately 7 inches long.

a^{2} + b^{2} = c^{2}  \\  5^{2} + 5^{2} = c^{2}  \\  25 + 25 = c^{2}  \\ 50= c^{2}  \\  \sqrt{50}= c \\ c=7.07
c ≈ 7

The hypotenuse is about 7 inches long.

From Midnight to 6 am the temperature rose 8 degrees C. At 6 am the temperature was -21 degrees C. What was the temperature at m
Alika [10]
Hello!

We know that from midnight to 6am the temperature went up 8° and at 6am it was -21°

To find what it was at midnight we have to work backwards

Since it went up we have to subtract 8 from -21

-21 - 8 = -29

The answer is -29°C

Hope this helps!
