Answer:
19°
Step-by-step explanation:
I have attached an image showing this elevation.
From the image, let's first find the angle A by using cosine rule.
Thus;
8.1² = 5.5² + 13.1² - 2(5.5 × 13.1)cos A
65.61 = 30.25 + 171.61 - 144.1cos A
144.1cos A = 171.61 + 30.25 - 65.61
144.1cosA = 136.25
cosA = 136.25/144.1
cosA = 0.9455
A = cos^(-1) 0.9455
A = 19°
2 1/24
Rewriting our equation with parts separated
2/3+1+3/8
Solving the fraction parts
2/3+3/8=?
Find the LCD of 2/3 and 3/8 and rewrite to solve with the equivalent fractions.
LCD = 24
16/24+9/24=25/24
Simplifying the fraction part, 25/24,
25/24=1 1/24
Combining the whole and fraction parts
1+1+1/24=2 1/24
Answer:
1st of all- (OFF TOPIC) you are on canvas lol
2nd- not sure, maybe B or C. Sorry if it is wrong, and I hope I could help.
Answer:
For a shape to be inscribed means that it's area is smaller than that of the other shape. Essentially, it's one shape inside another.
View my crudely drawn example for visualization. There, the square-ish shape is inscribed in the circle.
(You can basically inscribe any shape within another.)
