Use the compass and ruler to construct the bisector of the angle given below.
rodikova [14]
Oh my. ALEKS brings back terrible memories, but I hope you managed to do this. You should’ve drawn a line splitting the angle perfect in two. I’m not exactly certain how to use the tool as I’ve never really gotten to to that topic, but I hope you did well. :)

I don't understand how to begin this problem
Ronch [10]
I would first add 5 and 2 together, then multiply that by 3. Finally you would subtract the 1. After solving for what is inside the parentheses you would multiply it by 2 for your final answer.

Need help with this geometry assignment due soon smart people and mark Brainly
skad [1K]

Answer:

1. a + b + c = 180

2. b + d = 180

3. d = a + c

Step-by-step explanation:

1. a + b + c = 180:

Angles in a triangle add up to 180

2. b + d = 180:

Angles in a straight line equal 180 because they are supplementary angles

3. d = a + c:

ΔACD is an exterior angle, and ΔACB is interior adjacent, hence ∠a and ∠c add up to ∠d

Find the length of EF
Lisa [10]

Answer:

9

Step-by-step explanation:

1. First, we need to set up an equation to find the value of x and then the length of EF.

2. We know that DG is equal to 33, so we can add all the three sections it's cut into altogether to get 33. Therefore, we get an equation of: 3x - 28 + 3x - 30 + x = 33

3. (Solving for x)

Step 1: Simplify both sides of the equation.

  • 3x - 28 + 3x - 30 + x = 33
  • (3x+3x+x) + (-28-30)=33
  • 7x - 58 = 33

Step 2: Add 58 to both sides.

  • 7x - 58 + 58 = 33 + 58
  • 7x = 91

Step 3: Divide both sides by 7.

  • \frac{7x}{7} = \frac{91}{7}
  • x = 13

4. Now that we know x is equal to 13, we can plug that value in for the expression 3x - 30.

  • 3(13)-30
  • 39 - 30
  • 9

Therefore, the length of EF is 9.
