Find the unknown length in the right triangle. If necessary, approximate the length to the nearest thousandth. A: 13in and B: 2

umka2103 [35]

Use Pythagorean theorem a^2 + b^2 = c^2
13^2 + 20^2 = c^2
169 + 400 = c^2
569 = c^2 Use square root property to get c by itself. So you find the square root of both sides
23.853 = c

How do you solve<br> y=7x-10 <br> y=-3

strojnjashka [21]

Answer:

x = 1

Answer:

a = 8 m

Step-by-step explanation:

Since, given is an isosceles right triangle.

So, by Pythagoras theorem:

${a}^{2} + {a}^{2} = {(8 \sqrt{2} )}^{2} \\ \\ 2 {a}^{2} = 128 \\ \\ {a}^{2} = \frac{128}{2} \\ \\ {a}^{2} = 64 \\ \\ a = \sqrt{64} \\ \\ a = 8 \: m$
