Answer:
Step-by-step explanation:
RS + ST = RT
6y + 3 + 4y + 7 = 60
6y + 4y + 3 + 7 = 60
10y + 10 = 60
10y = 60 - 10
10y = 50
y = 50/10
y = 5
RS = 6*5 + 3 = 30 +3 = 33
ST = 4*5 + 7 = 20 + 7 = 27
The side opposite the lasrgest angle will also be the largest side in the triangle
Here it s 5.5 cms.
so using the given ratios we have
2/11 = x /5.5 where x is the smallest side (opposite the smallest angle)
x = (2*5.5) / 11 = 1 cm.
Let the number of reptiles on endangered list be 'x'
2x + 16=158
2x=158-16
2x=142
x=71
So there are 71 reptiles on the endangered list
