Answer:
y = 81°
Step-by-step explanation:
let the 5 th angle in the pentagon be x
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5, then
sum = 180° × 3 = 540°
sum the angles and equate to 540
x + 95 + 125 + 116 + 105 = 540
x + 441 = 540 ( subtract 441 from 540 )
x = 99°
x and y are adjacent angles and supplementary, sum to 180° , that is
x + y = 180°
99° + y = 180° ( subtract 99° from both sides )
y = 81°
Answer:
x= -3

Answer:
Option B) 100
Step-by-step explanation:
we know that
For a total number of 80 students , the number of boys that prefer soccer is equal to 10 (based on the table)
so
using proportion
Find out the number of boys that prefer soccer for a total number of 800 students
A. The circumference of a circle is the diameter times 3.14 aka pie and for instance, if you have two circles, circle A has a radius of 2 and diameter of 4 and circle B has a radius of 4 and diameter of 8, then if you compare the radius to the diameter (2/4 and 4/8) you get 1/2 for both and you know the circles are similar
The answer is 4x2-5x;Area= 114 in<span>2 i think</span>
