Find all three angles of the triangle x-5 x+10 x-35
Alexus [3.1K]

Answer:

See below ~

Step-by-step explanation:

<u>Given</u> : 3 angles of a Δ

  • (x + 5)°
  • (x + 10)°
  • (x + 15)°

<u>Solving</u> :

  • According to Angle Sum Property of a triangle, the angles of a triangle add up to 180°
  • x + 5 + x + 10 + x + 15 = 180
  • 3x + 30 = 180
  • x + 10 = 60
  • x = 50

<u>Finding the angles</u>

  • x + 5 = 50 + 5 = 55°
  • x + 10 = 50 + 10 = 60°
  • x + 15 = 50 + 15 = 65°

What are the solutions of this quadratic equation?X2 - 10x= -34A.r=-8, -2B.r= 5 + 3iC.r=-5 + 3iD.r=-5 + 159
ololo11 [35]

The given equation is-

x^2-10x=-34

First, we move the independent term to the other side.

x^2-10x+34=0

Now, we have to use the quadratic equation to find the solutions.-

x_{1,2}=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}

Where, a = 1, b = -10, and c = 34.

Replacing these values in the formula, we have.

\begin{gathered} x_{1,2}=\frac{-(-10)\pm\sqrt[]{(-10)^2-4(1)(34)}}{2(1)} \\ x_{1,2}=\frac{10\pm\sqrt[]{100-136}}{2}=\frac{10\pm\sqrt[]{-36}}{2} \end{gathered}

But, there's no square root of -36 because it's a negative. To solve this issue, we use complex numbers that way, we would have solutions.

x_{1,2}=\frac{10\pm\sqrt[]{36}i}{2}=\frac{10\pm6i}{2}=5\pm3i<h2>Therefore, the solutions are</h2>\begin{gathered} x_1=5+3i \\ x_2=5-3i \end{gathered}The right answer is B.
