Lake County’s smallest forest preserve is 472 acres. Orange County’s smallest preserve is 482 acres. Find the ratio of the acrea
photoshop1234 [79]

Answer:

Ratio is 236 : 241

Step-by-step explanation:

Lake County’s smallest forest preserve is 472 acres. Orange County’s smallest preserve is 482 acres

Lake County’s smallest forest = 472

Orange County’s smallest = 482

To find ratio we make a fraction

Ratio = Lake County’s  forest / Orange County’s forest

= \frac{472}{482}

Now simplify the fraction

divide top and bottom by 2

\frac{236}{241}

Ratio is 236 : 241

Find the measure of each angle of triangle abc, given ac=6, cb= 2 square roots of 3, and ab= 4 square roots of 3
Mazyrski [523]
Note that 
(4sqrt3)^2 = (2sqrt3)^2 + 6^2     [ 48  =   12 + 36]  so the triangle is  a right angled one with hypotenuse AB 

So angle C = 90 degrees

sin A =   2 sqrt3 / 4 sqrt3 = 1.2  giving A = 30 degrees
and B = 90 - 30 = 60 degrees


A = 30, B = 60 and C = 90 degrees
