Four of the angles of a pentagon measure 85°, 110°, 135°, and 95°. Find the measure of the missing angle. A. 115° B. 95°C. 135°D. 85°
Answers
Hence the missing angle is 115 degrees
Sum of angle in a pentagon
The sum of an interior angle of a pentagon is 540 degrees
Let the value of the fifth angle be "x", hence;
x + 85°+ 110° + 135° + 95° = 540
x = 540 - (85°+ 110° + 135° + 95°)
x = 540 - 425
x = 115 degrees
Hence the missing angle is 115 degrees

85 + 110 + 135 + 95 = 425
540 - 425 = 115
missing angle = 115° (answer is A)

AC=c/3
BD=4-c
Answers
Answer:
Recall the following result:
In a rectangle ABCD, the diagonals AC and BD are equal to each other, that is, AC = BD.
Consider the following statement:
and BD =4-c
The objective is to find the length of each diagonal.
As per the result:
In a rectangle ABCD:
AC = BD
Substitute the given values:
Multiply both sides by 3:
Simplify:
c = 12-3c
Add 3c to both sides :
4c= 12
Divide both sides by 4;
c = 3
Then,
BD=4-3 = 1
Therefore, the length of each diagonal is, 1.

The equation for nine times a number y subtracted from 85 is seven times the sum of four, and y is 85 - 9y = 7(4 + y).
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation in the word is "Nine times a number y subtracted from 85 is seven times the sum of four and y"
Let the number is y:
The nine times a number = 9y
Subtract from 85:
85 - 9y
Seven times the sum of 4 and y = 7(4 + y)
Now on equating:
85 - 9y = 7(4 + y)
Thus, the equation for nine times a number y subtracted from 85 is seven times the sum of four, and y is 85 - 9y = 7(4 + y).

Answer:
85 - 9Y = 7(4 + Y)
Step-by-step explanation:
Nine times a number Y. = 9 * Y = 9Y
subtracted From 85 = 85 - 9Y........... Equation 1
seven times sum of 4 and Y = 7(4 + Y)....... Equation 2
Equate Equation 1 and 2
85 - 9Y = 7(4 + Y)
