Answer:
1
Step-by-step explanation:
Let us consider the case of 3 numbers: x, y, and z.
Then x/x+y+z + y/x+y+z + z/x+y+z = x+y+z/x+y+z = 1
The same works also for any quantity of numbers.
Fist lets find the % of people using boats
100%- (36+53+2)= 9%
then find the number of people of 9%
200= 100%
B=9%
100B=200x9
B= 18
Always do brackets first
a) -40/10 = -4
b) 36/4 -2 = 7
c) -2 x 7 = -14
Solution:
We have to prove that ,
△ABC ~ △Z Y X Using SAS.
It is given that , ∠X ≅ ∠C .
You must keep in mind when two triangles are similar by S A S
1. The included side between the angle should be Proportional.

2. We have to prove that ,
△ABC ~ △Z Y X Using SAS.
It is given that , ∠B ≅ ∠Y .
The included side between the given angle should be Proportional.

3. We have to prove that ,
△ABC ~ △Z Y X Using SSS.
The three sides of two triangles must be Proportional.
