Tangent Θ = opposite / adjacent
AB = short leg = opposite = 12
AC = long leg = adjacent = 5
BC = hypotenuse = 13
tangent Θ = 12/5 ⇒⇒⇒ this is in ratio form
tanΘ = 2.4 ⇒⇒⇒ this is in decimal form
Answer:
20.833 feet
Step-by-step explanation:
The light reflects off the mirror at the same angle that it hits it at. So the triangle formed by the beam and mirror is similar to the triangle formed by Kevin and the mirror.
Therefore, we can write and solve a proportion.
h / 10 = 6.25 / 3
h = 20.833
The beam is 20.833 feet tall.

For #30 I ended up doing a lot of adding & if I’m correct it would take about 3 to 3 & 1/2 years for Marshall & Jim to end up with the same salary. So if I’m correct the equation would be the salary + the raise. So it would be something like s + r =x. X equals the total amount of the salary + the raise put together.
For #32 I wrote it down multiple times to make sure I get it right. I ended coming up with 46<-8x8<-6x. I tried figuring out the answer to that but I didn’t understand so I went on Socratic & it said there was no solution. Yeah
Sorry I couldn’t help with the other 2. I tried my best here.
