Answer:

X will equal 10 x=10

Step-by-step explanation:

First subtract 100 from both sides to get x^2-20x=-100 then find c. (-b/2)^2 is the formula. then c=100 so add 100 to both sides. x^2-20x+100=200. Then Factor. (x-10)^2=0 is what you should get. then do square root. x-10=0. So now add 10 to both sides and you get x=10. Tada!

How do i find the value of x , i’m so confuseddd !

olasank [31]

Answer:

x ≈ 61.3

Step-by-step explanation:

Using the Sine rule, that is

$\frac{6}{sinx}$ = $\frac{5.8}{sin58}$ ( cross- multiply )

5.8 × sinx = 6 × sin58° ( divide both sides by 5.8 )

sin x = $\frac{6sin58}{5.8}$ ≈ 0.87729, thus

x = $sin^{-1}$ (0.87729) ≈ 61.3
