Answer: See steps below for answer
Step-by-step explanation:
1) Set up an equation
- 40 + x + 3x = 180
- 4x + 40 = 180
- 4x = 140
- x = 35
_____
Part 2:
One angle: 40 degrees
Second angle: x or 35 degrees
Third angle: 3x or 105 degrees
Therefore answer is
35, 40, 105
They are the equilateral triangle,the square,and the regular pentagon

Answer:
58
Step-by-step explanation:
(2)(4) + (2)(-√-100) + (√-25)(4) + (√-25)(-√-100)
= 8 - 20i + 20i + 50 = 58
Answer:
70 ft
Step-by-step explanation:
let the distance be x.
then 45/x=sin 40
x=45/sin 40≈70
