Hi there!
We can solve for x knowing that the sum of interior angles in a triangle is 180°.
The square at the bottom indicates a right angle, or 90°. Therefore:
180 = 90 + x + (x + 10)
Combine like terms:
180 = 100 + 2x
Subtract 100 from both sides:
180 - 100 = 2x
80 = 2x
Divide both sides by 2:
x = 40.
Answer:
I am gonna take a guest and say <em>178</em> for number 3. And for number 4, the answer is <em>44.</em>
Step-by-step explanation:
For number 3, I added 76 and 102 which equals 178. For number 4, I put n+6+3n-10=180 because its a triangle. Do the math and you get n=44. Correct me if I am wrong; I tried my best.

Answer:
- 85 flashlights
- 17 sleeping bags
Step-by-step explanation:
One group of 5 flashlights and 1 sleeping bag will cost ...
$12×5 +45 = $105
