Answer:

1.) m∠A +m∠B +m∠C = (sum of angles in a triangle △)

2.) 24° + x + m∠C = 180°

3.) x = 156° - m∠C

step-by-step explanation:

1. m∠A +m∠B +m∠C = (sum of angles in a triangle △)

2. 28°+x−4° + ______ = 180°

24° + x + m∠C = 180°

3) x = 180° - 24° - m∠C

x = 156° - m∠C

Can someone help me!<br> if something cost $4.90 due to a 14% discount what is the original price
Vlad [161]

Answer:

$4.21

I NEED HELP!!!!!! 4x+2x-5=7x-1
yan [13]

Let's solve your equation step-by-step.

4x+2x−5=7x−1

Step 1: Simplify both sides of the equation.

4x+2x−5=7x−1

4x+2x+−5=7x+−1

(4x+2x)+(−5)=7x−1(Combine Like Terms)

6x+−5=7x−1

6x−5=7x−1

Step 2: Subtract 7x from both sides.

6x−5−7x=7x−1−7x

−x−5=−1

Step 3: Add 5 to both sides.

−x−5+5=−1+5

−x=4

Step 4: Divide both sides by -1.

−x

−1

=

4

−1

x=−4

Answer:

x=−4

Answerrr? Please I need help
nadezda [96]

Answer:

21

Step-by-step explanation:

f^{3} + 11g - 4h

f = 3, g = 2 and h = 7.

Substitute the above values into the expression.

3^{3} + 11 × 2 - 4 × 7

Since there's no addition, subtraction or division signs between 11g and 4h, this basically shows that it is multiplied. Simplify further...

3^{3} is 3×3×3 which equals to 27

11 × 2 equals to 22, and

-4 × 7 = -28

Put all these found values into an expression.

27 + 22 - 28

Use the B.O.D.M.A.S. rule. First we have to add then subtract.

(27 + 22) - 28

49 - 28 = 21

  • Length of an arc = 2 pi r (theta/360)
  • We needed to find theta(angle) here
  • Easily putting all the values gives us 115°
