In the diagram below, DE and EF are tangent to O. Which equation could be solved to find X, the measure of DF.

Brut [27]

Answer:

The answer to your question is letter D

Step-by-step explanation:

Formula

m∠E = $\frac{1}{2} ( DGF - DF)$

Data

m∠E = 48°

DGF = 228°

DF = x°

Substitution

48° = $\frac{1}{2} ( 228° - x°)$

Solution

2(48) = 228 - x°

96 = 228 - x°

96 - 228 = - x°

- 132 = - x°

x° = 132°

Complete the square to the problem X^2+6x-16=0

marishachu [46]

Answer:

Step-by-step explanation:

$(a+b)^2=a^2+2ab+b^2\qquad(*)\\\\-------------------------------\\\\x^2+6x-16=0\qquad\text{add 16 to both sides}\\\\x^2+6x=16\\\\x^2+2(x)(3)=16\qquad\text{add}\ 3^2\ \text{to both sides}\\\\\underbrace{x^2+2(x)(3)+3^2}_{(*)}=16+3^2\\\\(x+3)^2=16+9\\\\(x+3)^2=25\Rightarrow x+3=\pm\sqrt{25}\\\\x+3=-5\ \vee\ x+3=5\qquad\text{subtract 3 from both sides}\\\\\boxed{x=-8\ \vee\ x=2}$
