Answer:
x = 71°
Step-by-step explanation:
The angles of any triangle will always amount to 180°.
Which means: (Angle of A) + (Angle of B) + (Angle of C) = 180°
Placing the known values into that equation will always let you know the third angle of any triangle.
(Angle of A) + (Angle of B) + (Angle of C) = 180°
(38°) + (71°) + (x) = 180°
109° + x = 180°
Solve for x by subtracting 109° from both sides
x = 180° - 109°
x = 71°
OR you can add the other two known angles 38° + 71° = 109°
This subtracted from the 180°
180° - 109° = 71°

Hey there!
First, let's identify the point. We always go x axis first, then y axis, so the point is at (3, 8).
From the graph, we see that it means the tree is 8 feet tall and three years old.
Let me know if this helps :)
To solve the problem you have to isolate or separate x from everything else. That means adding 3 to both sides to start.
Answer: 402.124 inches²
Step-by-step explanation:
What is a cylinder?
A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centres overlap each other to form a right cylinder.
The surface area of a cylinder is the sum of the area of the base and the lateral area of the curved cylinder.
Given that the diameter of the cylinder is 8 inches, while the height of the cylinder is 12 inches. Since the radius is half the length of the diameter. Therefore, the radius of the given cylinder is 4 inches.
Now, the surface area of the cylinder is,
Surface area of the cylinder = Area of the bases + Area of the curved surface
= 2(πr²) + 2πrh
= 2(π × 4²) + (2 × π × 4 × 12)
= 2(50.265) + 301.5928
= 100.5309 + 301.5928
= 402.124 inches²
Hence, the surface area of the cylinder is 402.124 inches².
