Answer:

15 hours

Step-by-step explanation:

$x$ is the number of hours that Liam volunteered in the first month

Total time he volunteered in the two months is 40 hours so

$x+1\dfrac{2}{3}x=40\\\Rightarrow x+\dfrac{5}{3}x=40\\\Rightarrow \dfrac{3x+5x}{3}=40\\\Rightarrow x=\dfrac{40\times 3}{8}\\\Rightarrow x=15$

Time he volunteered in the first month is 15 hours.

What is the value of x?

Marysya12 [62]

A triangle always adds up to 180 degrees:

Therefore, 48 + 6x + 9x-3 = 180

Solve for x:

180 - 45 = 15x
135 = 15x

x = 9 degrees

All you need to do for angles like GBH is work out the angle at point B. With questions like this, work out the angle at the letter in the middle.
