You'd take the 1 and separate it from the 3/4
Answer:
1. 14.5
2. 16
Step-by-step explanation:
1. a^2 + b^2 =c^2
20^2 + 21^2 = c^2
400 + 441 = c^2
841 = c^2
=
29 = c
29/2 = x
14.5 =x
2. c^2-b^2 = a^2
34^2 - 30^2 = a^2
1156 - 900 = a^2
256 = a^2
=
16 = a
Hello!
The ratio of 1:5
The ratio we are find is 3 : x
