Answer:

x = 154/13

Step-by-step explanation:

You are given the measures of all three angles in a triangle

so according to the Triangle Sum Theorem:

∠MNO + ∠OMN + ∠NOP = 180

1. Substitute the measures of the angles into the equation:

(3x + 11) + (2x + 20) + (8x - 5) = 180

2. Combine like terms:

(3x + 2x + 8x) + (11 + 20 -5) = 180

13x + 26 = 180

3. Isolate x by subtratcing 26 from both sides

13x + 26 -26 = 180 -26

13x  = 154

4. Solve for x by dividing both sides by 13

13x/13 = 154/13

x = 154/13

7nadin3 [17]

Answer:

  • (3, -3)

Step-by-step explanation:

<u>Given:</u>

  • G = (11,-5)
  • M = (4,-4)
  • R = ?

<u>Solution</u>

  • R(x, y)

<u>As per midpoint formula;</u>

  • 4 = (11 + x)/2  ⇒ x + 11 = 8 ⇒ x = 3
  • -4 = (-5 + y)/2 ⇒ y - 5 = -8 ⇒ y = -3
  • R = (3, -3)
