Answer:

145°

Step-by-step explanation:

The angle of a straight line will always be 180.

The sun of all angles in a triangle will always be 180.

We can find the value of angle c by taking 145 away from 180.

180 - 145 = 35

Now that we know angle c, to find the sum of angles a and b, we take 35 away from 180.

180 - 35 = 145

Answer:

45 degrees

Step-by-step explanation:

You can see that angle C is obtuse and Angle A and B are obviously not obtuse or right angles, so the only answer left is 45

Soloha48 [4]

as you already know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".

$\bf \textit{Logarithm Cancellation Rules} \\\\ log_a a^x = x\qquad \qquad \stackrel{\textit{we'll use this one}}{a^{log_a x}=x} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \stackrel{f(x)}{y}=\log_2(x+1)\implies \stackrel{\textit{quick switcheroo}}{\underline{x}=\log_2(\underline{y}+1)}\implies 2^x=2^{\log_2({y}+1)} \\\\\\ 2^x=y+1\implies 2^x-1=\stackrel{f^{-1}(x)}{y} \\\\[-0.35em] ~\dotfill\\\\ 2^2-1=f^{-1}(2)\implies 3=f^{-1}(2)$
