Answer:

  x = 5.4

Step-by-step explanation:

The segment sum theorem tells you ...

  AB +BC = AC

  36 +(5x -9) = 54

  5x = 27 . . . . . . . . . . . subtract 27 from both sides

  x = 5.4 . . . . . . . . . . divide by 5

Find m∠1<br><br> A. 38 degrees<br> B. 42 degrees<br> C. 52 degrees<br> D. 78 degrees
Zepler [3.9K]
Let's solve this problem step-by-step.

Let's first establish the following formula:

Angle sum of a triangle = 180°

Also, note that the square shape in the top-right corner of the triangle indicates that it is a right-angle. This means that, that angle is equal to 90°.

Now, let's establish the equation we will be using to solve this problem based on the previous information as displayed below:

m + 38° + 90° = 180°

We will now simply solve the equation in order to obtain the value of ( m ) as display below:

m + 38° + 90° = 180°

m = 180 - 38 - 90

m = 52°

ANSWER:

Therefore, the answer is:

C. 52 degrees.
