The sides of a triangle are in the ratio 2:3:4 and the longest side is 20 cms longer than the shortest side. Compute the length of each side.

90cm

Step-by-step explanation: 2x, 3x, and 4x is what your dealing with and you know the longest side (4x) is 20cm longer than the shortest side(2x) which means 4x-2x = 20 because of the difference. Solved is 2x = 20 and X equals 10 and since this is a ratio the x values are the same so all sides equals 2(10)+3(10)+4(10)= 90

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
