The interior angle measures are 900 degrees
131+122+125+148+107+126 = 759
900-759 =141
X = 141
Answer: Choice C) 115 degrees
--------------------------------
Explanation:
The three angles are 42, 73 and 65 degrees. Let's call them x,y, and z respectively
x = 42
y = 73
z = 65
To find an exterior angle for x, we subtract the given angle x from 180
180-x = 180-42 = 138
The exterior angle adjacent to angle x is 138 degrees. This isn't listed so we move on
Do the same for y
180-y = 180-73 = 107
This isn't listed either. So we move on
Repeat for angle z
180-z = 180-65 = 115
This is listed as choice C. That's why choice C is the answer
Answer:676/25
Step-by-step explanation:
when r=1
(5(1)+1/5)^2
(5+1/5)^2
((25+1)/5)^2
(26/5)^2
676/25
Answer: x = 12 ft
Step-by-step explanation:
let the erect part of the pole be x
the slanted part of the pole will be 25-x
the ground distance = 5
they form a right triangle
apply Pythagoras theorem
5^2+x^2=(25-x)^2
25+x^2=x^2 - 50x + 625
50x=625-25
50x=600
x=600/50
x=12 feet
