55

Step-by-step explanation:

add angles: x+45x-5+55 = 2x +50

180=50 = 130

130-20 = 110

110/2 = 55

55

26°

Step-by-step explanation:

Sum of angles in a triangle = 180°

x° + 55° + (4x - 5)° = 180°

5x + 50° = 180°

5x = 180° - 50°

5x = 130°

x = 130/5

x = 26°

a² + b²= c²

24² + 7² = c²

c= 25

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
