In circle K, what is the value of x?
djyliett [7]

Answer:

18°

Step-by-step explanation:

A diameter cuts a circle into two arcs that are each 180°. An inscribed angle that intercepts an arc of 180° has a measure of 90°. Thus we have ...

... 5x = 90°

.. 90°/5 = x = 18°

Find the equation of a line which is parallel to y= 2/5 x + 17 and passes through (-15,12)
Naddika [18.5K]

Answer:

y = 2/5x + 18.

Step-by-step explanation:

The line will have the same slope of 2/5.

Using the point-slope form of a line:

y - 12 = 2/5(x - -15)

y - 12 = 2/5(x + 15)

y = 2/5x + 6 + 12

y = 2/5x + 18.

The walls are vertical so the angle opposite X would be a right angle which is 90 degrees.

X would be 180 - 90 - 35 = 55 degrees

X and 2y - 5 are complementary angles which add together to equal 90:

2y - 5 + 55 = 90

Simplify:

2y +50 = 90

Subtract 50 from both sides:

2y = 40

Divide both sides by 2:

y = 20

alexdok [17]

Interpreting the situation, it is found that Marjorie will have 240 left after paying her penalty.

---------------------

  • When the piece lands on the red square, the penalty is equal to <u>30 times the sum they roll on two numbers.</u>
  • Marjorie rolls 4 and 2, thus, the sum is 6.
  • The penalty is of 6 \times 30 = 180
  • She currently has 420, the penalty removes 180, thus, she will have 420 - 180 = 240 left after paying her penalty.
