Answer:
RC1. 5
RC2. 8
RC3. a
RC4. 3
Step-by-step explanation:
So basically what you need to start with is the fact that the second triangle is 2 times larger than the first.
so,
8 = 8
C = 10
A = 6
---------------------------------------------------------------------
the next important part is that the opposite sides of the fraction, when multiplied are equal to each other.
( for example 1/2 = 2/4, because 1*4 = 4 and 2*2 = 4)
RC1. a/3 = C/_
substitute
6/3 = 10/_
3 * 10 = 30
6 * _ =30
30/6 = 5.
Rc2. 4c = 5_
4*10 = 5*_
40/5 = 8
RC3. 3c = 5*_
3*10 = 5*_
30/5 = 6
RC4. 4a = 8*_
4 * 6 = 8*_
24/8 = 3
good luck with your schoolwork/homework!
