Answer:

A = 84º

B = 74º

C = 22º

Step-by-step explanation:

Since all the three angles of a triangle have to add up to be 180º, one can do...

A + B + C = 180º

So,

(4x+12) + (3x+20) + (x+4) = 180º

8x + 36 = 180º

8x = 144

x = 18

Then you just substitute x in each of the angles

A = 4(18) + 12 = 84º

B = 3(18) + 20 = 74º

C = (18) + 4 = 22º

***Math Check: 84 + 74 + 22 = 180º

Solve the equation in the complex number system.
tatiyna
To get rid of x^{3}, you have to take the third root of both sides:
\sqrt[3]{x^{3}} = \sqrt[3]{1}
But that won't help you with understanding the problem. It is better to write x^{3}-1 as a product of 2 polynomials:
x^{3}-1 = (x-1)\cdot (x^{2} +x +1)
From this we know, that x-1 = 0 => x = 1 is the solution. Another solutions (complex roots) are the roots of quadratic equation.
