Determine which length form a right triangle
To do this, we make use of Pythagoras theorem where the square of the largest length = the sum of the squares of the other lengths
So:
(1) 12, 35, 37 --- Yes
(2) 16, 30, 34 --- Yes
(3) 18, 24, 42 --- No
(4) 20, 21, 29 -- Yes
Answer:
Your answer is C, (3k+4)(2k-5)
Step-by-step explanation:
A = 40° (Vertically opposite angles)
b = 180 - 90 - 40 = 50° (Angles in a triangle add up to 180)
c = 180 - 65 = 115° (Adjacent angles on a straight line)
The number of squares tiles that will be required to floor the rectangular store is approximately 1284 tiles
<h3>How to find the number of tiles used for the rectangular floor?</h3>
The rectangular store measures 6.5m by 7.9m.
Therefore,
area of a rectangle = lw
where
Therefore,
area of a rectangle = 6.5 × 7.9
area of a rectangle = 51.35 m²
The square tiles used for the floor is 20cm each. Therefore,
20 cm = 0.2m
hence
area of the square tile = 0.2² = 0.04 m²
number of tiles = 51.35 / 0.04 = 1283.5
number of tiles ≈ 1284 tiles
