First triangle:
2x+2x+x=180
x=36
second triangle:
7x+3x+90=180
x=9
third triangle:
2x+x+x=180
x=45
good luck!!
Use a projector do you have one?

Answer:</h2>
The constraint which represent a thriving population of penguins at the zoo is:
0 < x ≤ 10 and 0 < y ≤ 20.
<h2>
Step-by-step explanation:</h2>
Let x = the number of female penguins and y = the number of male penguins.
Now, it is given that:
The group needs two times more males than females to thrive, and the zoo only has room for 10 female penguins.
This means that:
0 < x ≤ 10
( Because there are no room for more than 10 penguins )
Also,
y= 2x
Since,
x>0
This means that: 2x>0
i.e. y>0
and x ≤ 10
i.e. 2x ≤ 20
i.e. y ≤ 20
Hence, the constraints which represent a thriving population of penguins at the zoo is:
0 < x ≤ 10 and 0 < y ≤ 20.

Answer:
B 3
Step-by-step explanation:
We can use the secant-secant formula:
(whole secant) x (external part) =
(whole secant) x (external part)
9 * 4 = 12 *x
36 = 12x
Divide each side by 12
36/12 =12x/12
3 =x
