Answer:

x = 6
y = 55

Step-by-step explanation:

Angles opposite congruent sides are congruent, so base angles D and F of this isosceles triangle have the same measure:

y = 55

The sum of angles in the triangle is 180°, so ...

55° +(11x +4)° +55° = 180°

11x = 66 . . . . . . . . divide by °, subtract 114

x = 6 . . . . . . . . . . .divide by 11

The values of x and y are 6 and 55, respectively.

Exponential to Logarithmic: $\displaystyle b^m=x \rightarrow log_bx=m$

Step-by-step explanation:

Step 1: Define

Identify

0.77 = log(x)

Step 2: Solve for x

[Equality Property] Raise both sides to the 10th power: $\displaysytle 10^{0.77} = 10^{logx}$
Simplify: $\displaysytle x = 10^{0.77}$
Evaluate: $\displaysytle x = 5.88844$
