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°
(A) I got 10(10)=100 points in remote space.
(B) I also got 10(9)=90 points in remote space
Answer:
x = 3/5
Step-by-step explanation:
4+4(x-2)=2(x+1)−x
Distribute
4+4x-8 = 2x+1-x
Rearrange and Simplify
4x - 4 = x + 1
Subtract x and add 4
3x = 5
Divide
x = 3/5
the length of SR is
.
<u>Step-by-step explanation:</u>
Here we have , On square PQRS below, if Q is located at (7,0) and R is located at (5,-8) . We need to find Length of side SR . Let's find out:
We know that , In a square there are 4 sides , and length of every side is same . So side length of SR = side length of QR . Now , Let's find side length of QR .
We know that distance between two points
given by :
⇒ 
Two points given are
:
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
But QR=SR , Therefore , the length of SR is
.
I think you left out x somewhere, check your equation
