Answer:

x = 22

Step-by-step explanation:

(x+1)+(3x+1) = 4x+2

4x+2=90°

Solve for x:

4 x + 2 = 90

Subtract 2 from both sides:

4 x + (2 - 2) = 90 - 2

2 - 2 = 0:

4 x = 90 - 2

90 - 2 = 88:

4 x = 88

Divide both sides of 4 x = 88 by 4:

(4 x)/4 = 88/4

4/4 = 1:

x = 88/4

The gcd of 88 and 4 is 4, so 88/4 = (4×22)/(4×1) = 4/4×22 = 22:

Answer: x = 22

$\bf log_{{ a}}(xy)\implies log_{{ a}}(x)+log_{{ a}}(y)\\\\

\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-----------------------------\\\\
ln(a+3)+ln(a-3)=ln(16)\implies ln[(a+3)(a-3)]=ln(16)
\\\\\\
ln[a^2-3^2]=ln(16)\impliedby \textit{removing ln() from both sides}
\\\\\\
a^2-9=16\implies a^2=16+9\implies a^2=25
\\\\\\
a=\pm\sqrt{25}\implies a=\pm 5$
