Answer:

C

Step-by-step explanation:

The degrees of a triangle add up to 180.

Angle C is already 90 degrees therefore angle A + angle B = 90 degrees.

Angle A is equal to sinA=1/2.

sinA=1/2 is equal to 30 degrees if you press 2nd, sin (1/2) into the calculator. You may also know this if you have memorized the values of trig.

90-30=60.

That leaves you with 60 degrees for angle B.

Find an equation of the line with the slope m=6 that passes through the point (4,4). Write the equation in the form Ax + By = C
Ainat [17]

Answer:

Y - 6x = - 20

Step-by-step explanation:

Y = 6x + c

Substituting the value of x and y

4 = 24 + c

Subtracting 24 from both sides

C = - 20

Y = 6x - 20

Subtracting 6x from both sides

Y - 6x =- 20

Circumference Formula: C = πd

  • <em>C</em> is circumference
  • <em>d</em> is diameter

Step-by-step explanation:

<u>Step 1: Define</u>

Diameter <em>d</em> = 28 mm

<u>Step 2: Solve</u>

  1. Substitute in variables [Circumference Formula]:                                          C = 3.14(28 mm)
  2. [Circumference] Multiply:                                                                                 C = 87.92 mm
