The sum of the interior angles in a triangle is 180.


We can find what one of angles are. Since the sum of two angles are 80, that leaves the third angle.

180-80=100


This means one angle equals 100.


We can make an equation to find what the two angles are. Let's have x as the smaller angle.

x+x+20=80; since their difference is 20.

2x+20=80; let's subtact 20.

2x=60; now divide by 2.

x=30


Since the smaller angle of the two is 30, the other is 50.


So, the angles of the triangle are 30°, 50°, and 100°

Sum of 2 angles = 80°

Difference = 20°

If we take away 20° from the sum, both angles are equal

⇒80 - 20 = 60°


Divide by 2 to find the smaller angle:

60 ÷ 2 = 30


Add 20° to find the bigger angle:

20 + 30 = 50°


<u>One of the angle is 30° and the other angle is 50°</u>


Given that the sum of the two angles is 80°

⇒ Third angle = 180 - 80 = 100°


Answer: The 3 angles are 30° , 50° and 100°

antiseptic1488 [7]

Answer:

  • n ≤ 606

Step-by-step explanation:

<u>Seven less than the product of a number n and 1/6 is no more than 94, translating:</u>

  • n*1/6 - 7 ≤ 94

<u>Solving for n:</u>

  • n/6  ≤ 94 + 7
  • n/6 ≤ 101
  • n ≤ 101*6
  • n ≤ 606
