The values of angles are 140 and 20
• In plane geometry, a figure which is formed by joining of two lines that share a common point is called as the angle. The two lines or rays are called as the sides of the angle and the common point is called the vertex.
• In geometry there are types of angles such as complementary angles, supplementary angles, acute angle, obtuse angles. Complementary angles are the angles whose sum is equal to 90. Supplementary angles are the angles whose sum is equal to 180.
According to the question
We are given that one angle is -7x and the other angle is -2x
Using formula of supplementary angles
-7x + (-2x) = 180
-7x -2x = 180
-9x = 180
-x = 20
x = -20
The value of x is -20
The value of angle – 7x = -7(-20) = 140
The value of angle -2x = -2(-20) = 40

Answer: 53.34 feet
Step-by-step explanation:
Let the length of the second piece of rope be x.
The first piece of rope is half as long as the second piece of rope. This will be: = x/2.
The third piece is three times as long as the second piece of rope. This will be: = 3 × x = 3x
Therefore,
x + 0.5x + 3x = 80
4.5x = 80
x = 80/4.5
x = 17.78 feet
The length of the longest piece of rope will be:
= 3 × x
= 3 × 17.78
= 53.34 feet
