Answer:
NC = 7.7
C = 63.6°
T = 26.4°
Step-by-step explanation:
✔️Apply pythagorean theorem to find the length of NC:
NC = √(17.2² - 15.4²) = √58.68
NC ≈ 7.7
✔️Apply trigonometric function to find Angle T:
Reference angle = T
Hypotenuse = 17.2
Adjacent length = 15.4
Apply CAH, thus:



T ≈ 26.4°
✔️C = 180 - (90 + 26.4) (sum of triangle)
C = 63.6°
Perimeter is the addition of all 4 sides and a square as all the same sides. so every side will be the same. so if you divide 216 by 4 you get 54. you can check this by adding 54+54+54+54=216 or 54x4=216
Step-by-step explanation:
Length = 5 cm and Breadth = 3 cm
Area of a rectangle = length × breadth
=(5×3) cm
2
=15 cm
2
Hence, Area of rectangle with length 5 cm and breadth 3 cm is 15 cm
