It could be: (x + 7/2)^2 = x^2 + 7x + 49/4
So you should add it by 49/4.

For triangle ABC C = 90 Side AC = 13.5 Side BC = 8.6 Find the measure of angle B​
MakcuM [25]

Answer:

57.5°

Step-by-step explanation:

For triangle ABC C = 90 Side AC = 13.5 Side BC = 8.6 Find the measure of angle B​

We solve using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

θ = Angle B

Opposite = Side AC 13.5

Adjacent = Side BC = 8.6

Hence:

tan θ = 13.5/8.6

θ = arc tan (13.5/8.6)

θ = 57.501354056°

Approximately = 57.5°

Therefore, Angle B = 57.5°

10 points for answering!<br> What is the answer to 13, 14, and 15?
ki77a [65]

Step-by-step explanation:

<h2>13. </h2>

\implies\sf{ {x}^{2} = 144 } \\  \\  \implies\sf{ x =  \pm \sqrt{144} }   \\  \\ \implies\sf{ x =  \pm 12 }

<h2>14.</h2>

\implies\sf{ {x}^{2} =  \dfrac{25}{289}  } \\  \\  \implies\sf{ x =  \pm \sqrt{ \frac{25}{289} } }   \\  \\ \implies\sf{ x =  \pm  \frac{5}{17}  }

<h2>15.</h2>

\implies\sf{ {x}^{3} = 216 } \\  \\  \implies\sf{ x =   \sqrt[3]{216}  }   \\  \\ \implies\sf{ x =  6 }
