Need help finding the missing angle
Nutka1998 [239]

Answer:

The missing dimension is

5

Step-by-step explanation:

The Pythagorean Theorem states that

{a}^{2}  +  {b}^{2}  =  {c}^{2}  \\

Note that c is the hypothenus <em>(</em><em>the</em><em> </em><em>hypothenus</em><em> </em><em>is</em><em> </em><em>always</em><em> </em><em>opposite</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>right</em><em> </em><em>angle</em><em> </em><em>of</em><em> </em><em>a</em><em> </em><em>triangle</em><em>)</em>

Therefore

{a}^{2}  +  {b}^{2}  =  {c}^{2} \\  {12}^{2}  +  {b}^{2}  =  {13}^{2} \\ 144 +  {b}^{2}   = 169 \\  {b}^{2}  = 169 - 144 \\  {b}^{2}  = 25

\sqrt{ {b}^{2} }  =  \sqrt{25}  \\ b = 5

Therefore the missing dimension is 5

I got it wrong anyone know the answer thank u!
Romashka-Z-Leto [24]

Answer:

Choice 4 (s - 3 = 12)

Step-by-step explanation:

I think you made a reading error on this question, as it said "for which equation is s = 9 <em>not</em> the solution?" No need to fret though, this can easily be solved by substituting 9 into the variable <em>s</em> of each equation.

1. We know it's not choice 1 (s + 6 = 15), because doing 9 + 6 does equal 15.

2. We know it's not choice 2 (7 + s = 19), because doing 7 + 9 does equal 16.

3. We know it's not choice 3 (13 - s = 4), because doing 13 - 9 does equal 4.

4. Choice 4 (s - 3 = 12) is the correct answer because doing 9 - 3 equals 6, not 12. Thus this equation is incorrect, meaning this is the correct choice.

Choice 4/D is the correct choice.
