Answer:

see explanation

Step-by-step explanation:

Use the sine ratio in the right triangle to find the hypotenuse h, and the exact value

sin45° = \frac{1}{\sqrt{2} } , then

sin45° = \frac{opposite}{hypotenuse} = \frac{20}{h}  = \frac{1}{\sqrt{2} } ( cross- multiply )

h = 20\sqrt{2}

-----------------------------------------------------------------------------

Use the tangent ratio to find the horizontal leg x and tan45° = 1 , then

tan45° = \frac{opposite}{adjacent} = \frac{20}{x} = 1 ( multiply both sides by x )

x = 20

PLEASE HELP!
Cloud [144]
The short answer is trial and error.  The side lengths "3" and "4" can both be substituted for a² and b² but not c² because their value squared is not high enough since 5² is 25. "c²" as to match the longest side because the smaller numbers will cause the equation to not be true. See Below. 

a² + b² = c²
3² + 4² = 5²
9 + 16 =  25
25 = 25
______________________________

a² + b² = c²
4² + 3² = 5²
16 + 9 = 25
25 = 25
______________________________

a² + b² = c²
5² + 4² = 3²
25 + 16 = 9
41 ≠ 9

______________________________

a² + b² = c²
3² + 5² = 4²
9 + 25 = 16
34 ≠ 16

Hope this helped!
