Answer:
∠A=30°
Step-by-step explanation:
let's call the angle at the bottom B and the one next to the 130 C
∠A=3x-6
∠C=180-130= 50°
vertical angles are equal∠B =8x+4
∠A+∠C+∠B=180°
find x:
3x-6+50+8x+4= 180°
11x+48=180°
11x= 132
x=12
find ∠A
∠A=3x-6= 3(12)-6 =30°

Answer: x = 35</h3>
==========================================================
Explanation:
All three angles must add to 180. This is true for any triangle.
x+x+110 = 180
2x+110 = 180
2x = 180-110 ... subtract 110 from both sides
2x = 70
x = 70/2 .... divide both sides by 2
x = 35
As a check: 35+35+110 = 180 which helps confirm the answer.
45 is b

<u>The function that represents the </u><u>volume</u><u> of the chest is </u><u>40.</u>
What is a volume simple definition?
- The amount of space occupied by a three-dimensional figure as measured in cubic units (as inches, quarts, or centimeters) cubic capacity.
- The amount of a substance occupying a particular volume.
When the Area of rectangular chest:
A(x) = 20√x /3
⇒ Volume of chest = Base area x Height
Therefore:
(X + 6) × 20√x /3
(20x√x /3 ) + (20 × 6√x/3)
(20x√x /3 ) + (20 × 2 × 3√x/3)
(20x√x/3) + 40√x
Therefore, the correct answer for the drop-down menu is that the first blank is multiply and the second blank is 40.
