Answer:

x = 137

Step-by-step explanation:

Remark

What you have is a cyclic quadrilateral. That is a 4 sided figure whose angle vertices touch the circle's circumference. The sum of angles opposite each other = 180 degrees.

Givens

<1 = 43 degrees

Sum of x and <1 = 180 degrees.

Solution

x + 43 = 180 Subtract 43 from both sides

x + 43-43 = 180-43 Combine

x = 137

Solve This Using The Quadratic Formula: 3x^2+9x-6=0

aivan3 [116]

<h3>Therefore either $x = \frac{-3+\sqrt{17}}{2}$ or, $x = \frac{-3-\sqrt{17}}{2}$ </h3>

Step-by-step explanation:

$3x^2 +9x -6=0$ $x = \frac{-b\pm\sqrt{b^2- 4ac} }{2a}$

$\Leftrightarrow x = \frac{-9\pm\sqrt{9^2- 4.3(-6)} }{2.3}$ here a = 3 ,b = 9 and c= -6

$\Leftrightarrow x = \frac{-9\pm\sqrt{153} }{6}$

$\Leftrightarrow x = \frac{3(-3\pm\sqrt{17}) }{6}$

$\Leftrightarrow x = \frac{-3\pm\sqrt{17}}{2}$

Therefore either $x = \frac{-3+\sqrt{17}}{2}$ or, $x = \frac{-3-\sqrt{17}}{2}$

What is the value of a when 3b−2a=17 and 4a+4b=−64?

ycow [4]

Answer:

(-b-81)/6=a

Step-by-step explanation:

3b−2a-17 = 4a+4b+64

3b-4b-17-64=4a+2a

-b-81=6a

(-b-81)/6=a
