Answer:
≈ 27 m
Step-by-step explanation:
Assuming the house is in the form of rectangle:
- Length = 17 m
- Width = 21 m
- Diagonal =?
As per Pythagorean,
- d = √l²+w² = √17² +21² = √289+441 = √730 ≈ 27 m
Answer:
B
Step-by-step explanation:
The sum of the 3 interior angles of a triangle = 180°
Check the sums of the given sets of angles
90° + 42° +58° = 190° ≠ 180° ← not valid
60° + 60° + 60° = 180° ← Valid
100° + 48° + 42° = 190° ← not valid
31° + 75° + 70° = 176° ← not valid
You're given an angle, the side adjacent to the angle, and are looking for the hypotenuse.
Use cosine = adjacent / hypotenuse.
cos(60) = 2√(3) / x
Rearrange the equation to solve for x (multiply both sides by x, then divide both sides by cos(60)).
x = (2√(3)) / (cos(60))
x equates to about 6.928
Then I'll definitely will ask you questions about maths :)
