b =51

Step-by-step explanation:

A straight line is 180 degrees

The three angles add to 180 degrees

90+39+b = 180

Combine like terms

129+b+180

Subtract 129 from each side

129+b-129 = 180-129

b =51

$b =5 1 \: \: \: degrees \\$

Step-by-step explanation:

Angles in a straight line =180 degrees

$90 + 39 + b = 180 \\12 9 + b = 180 \\ b = 180 - 129 \\ b =5 1 \: \: \: degrees$

hope this helps

brainliest appreciated

good luck! have a nice day!

$\bf f(x)=y=ln(x)\qquad 
\begin{cases}
x=1\\
y=ln(1)\to y=0
\end{cases}\\\\
-----------------------------\\\\
\left. \cfrac{dy}{dx}=\cfrac{1}{x} \right|_{x=1}\implies 1\impliedby m
\\\\\\
\textit{now, we know that }
\begin{cases}
x=1\\
y=0\\
m=1
\end{cases}\implies y-0=1(x-1)\implies y=x-1$

now, you're asked to use it when ln(1.38), which is just another way of saying x = 1.38

so set x = 1.38 and see what "y" is
