Answer:
option 2
Step-by-step explanation:
The problem can be solved using Pythagoras' identity for a right triangle.
The angle between due East and due North is 90°
The solution here involves using the Cosine rule.
let x be the direct distance between house and office, then
x² = 17² + 21² - 2(17)(21)cos90° → option 2
Note that since cos90° = 0 the equation reduces to
x² = 17² + 21² ← Pythagoras' identity
Answer:
x=7
Step-by-step explanation:
This is a vertical line. Vertical lines are of the form x=
The x coordinate is 7
x=7
B. 12 assuming that it is a right triangle :)
Answer:
c i think
Step-by-step explanation:
Answer:
A. 7 centimetres and 25 centimetres
Step-by-step explanation:
To see if the lengths make a triangle, use the Pythagorean theorem. Insert the biggest value as c (the hypotenuse, which is always the longest side in a right triangle). If both sides equal each other, it is a right triangle:
A.
This is a right triangle.
B.
Not a right triangle.
C.
Not a right triangle.
D.
Not a right triangle.
Done :D
