What are Complementary Angles?Complementary angles are those whose combined angle is 90 degrees or less. To put it another way, two angles are said to be complimentary if they combine to make a right angle.
Two angles are said to be complementary if their sum is 90 degrees. By deducting an angle from 90, one can find its complement.
For instance, 90° - 40° = 50° is the complement of 40°.
Given:
m∠A = 37° and m∠B = (3x + 17)°
As, the sum of Complementary angle is 90.
<A + <B= 90
37 + 3x+ 17 = 90
3x + 54 = 90
3x = 36
x= 12
Hence, the value of x is 12.

y/x= abc
Answer:
x=y/abc
Step-by-step explanation:
Let's solve for x.
y/x=abc
Step 1: Multiply both sides by x.
y=abcx
Step 2: Flip the equation.
abcx=y
Step 3: Divide both sides by abc.
abcx/abc=y/abc
x=y/abc
Answer:
x=y/abc
Step-by-step explanation:
In order to make x the subject:
Isolate the variable by: ...
Rearrange the equation so each term containing x is on the same side of the =.
Factorisation may be needed if there are multiple terms containing x . ...
Perform an operation to ensure only a single x variable is left as the subject.

D. 15.
How to simplify the expression?The expression for this problem is defined as follows:
2³ + 6/3 - (-10/2)
The parenthesis takes precedence, hence:
2³ + 6/3 - (-5) = 2³ + 6/3 + 5
The power takes precedence, hence:
8 + 6/3 + 5
Division has higher precedence than addition, hence:
8 + 2 + 5.
Hence the result is given as follows:
8 + 2 + 5 = 15.

A regular polygon is shown, with the measure of one of its angles labeled 3x − 15.
8 sided regular polygon with one angle labeled 3 times x minus 15
Determine the value of x.
x = 40
x = 65
x = 50
x = 135
Answer:
x = 50
Step-by-step explanation:
The interior angle at each vertex of regular octagons are 135°.
3(50) - 15 = 135
For the polygon to be an 8 sided regular polygon like you said, the angle must equal 135, and so x must equal 50.
The required value of the x in the given expression is 50°.
Given that,
A regular polygon is shown, with the measure of one of its angles labeled 3x − 15.
What is a polygon?
A polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,
Examples of polygons, equilateral triangles, squares, pentagons, etc
Here,
For the octagon,
The angle of a vertex is 135°.
Equating the angles,
3x -15 = 135
3x = 135 + 15
3x = 150
x = 50
Thus, the required value of the x in the given expression is 50°.
