Triangle <br> solve for x<br> (14x - 23)°<br> (5x - 7)°<br> (6x + 14)°
damaskus [11]

Answer:

the value of x = 10°

Step-by-step explanation:

here's the solution :-

we know that, the measure of exterior angle of the triangle is equal to the sum of opposite two interior angles.

so,

=》5x - 7 + 6x + 14 = 14x - 23

=》11x + 7 = 14x - 23

=》7 + 23 = 14x - 11x

=》3x = 30

=》x = 30 ÷ 3

=》x = 10°

2/x-5=4x<br><br> What is the value of x
kati45 [8]

Answer:

\large\boxed{x=\dfrac{5\pm3\sqrt3}{2}}

Step-by-step explanation:

Domain:\ x-5\neq0\to x\neq5\\\\\dfrac{2}{x-5}=4x\\\\\dfrac{2}{x-5}=\dfrac{4x}{1}\qquad\text{cross multiply}\\\\(4x)(x-5)=(2)(1)\qquad\text{use the distributive property}\\\\(4x)(x)+(4x)(-5)=2\\\\4x^2-20x=2\\\\2^2x^2-20x=2\\\\(2x)^2-2(2x)(5)=2\qquad\text{add}\ 5^2\ \text{to both sides}\\\\(2x)^2-2(2x)(5)+5^2=2+5^2\qquad\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\(2x-5)^2=2+25\\\\(2x-5)^2=27\to2x-5=\pm\sqrt{27}\qquad\text{add 5 to both sides}

2x=5\pm\sqrt{9\cdot3}\qquad\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\2x=5\pm\sqrt9\cdot\sqrt3\\\\2x=5\pm3\sqrt3\qquad\text{divide both sides by 2}\\\\x=\dfrac{5\pm3\sqrt3}{2}
