F(1)=(0)(-1)=0
f(2)=(1)(0)=0
f(3)=(2)(1)=2
f(4)=(3)(2)=6
Step-by-step explanation:
Let a, b, c be the measures of the interior angles and x, y, z be the measures of the exterior angles of the triangle. Where x and adjacent to a, y is adjacent to b and z is adjacent to c.
By interior angle sum postulate of a triangle:
a + b + c = 180°... (1)
Therefore, by remote interior angle theorem:
x = b + c.... (2)
y = a + c..... (3)
z = a + b.... (4)
Adding equations (2), (3) & (4)
x + y + z = b + c + a + c + a + b
x + y + z = 2a + 2b + 2c
x + y + z = 2(a + b + c)... (5)
From equations (1) & (5)
Thus, the sum of exterior angles so formed is equal to four right angles.

4(x+6)
to get the area you multiply the sides and you can represent that with parentheses

Answer:
he would have to be at the mountain by 7:45
Step-by-step explanation:
if I'm not mistaken it would take him six hours in total to be up and down the mountain and 7:45 - 1:45 = 6
7 females to 17 males
I divided both sides by 3
