The measure of two vertical angles are represented by (4x - 7) and (2x +13). What is the sum of the two angles measures?

Step-by-step explanation:

Vertical angles by definition are congruent.  That means that

4x - 7 = 2x + 13 and

2x = 20 so

x = 10.

The sum of the 2 angles is 10(2) = 20

answer: it is d

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}
