Aliving room is shaped like a pentagon. a carpenter wants to put a triangular shelf in the corner marked on the diagram. the sum of the interior angles of a pentagon is 540°. which statement is correct?

a.) the shelf angle is too small because the corner is more than 70°.
b.) the shelf angle is too big because the corner is less than 70°.
c.) the shelf will fit exactly because the corner is 70°.
d.) it cannot be determined if the shelf will fit in the corner.

answer: sensy

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x
