If the quadrilateral below is a rhombus, find the missing measures.
1 answer:
Answer:
- corner angles are 80° (∠JKL) and 100° (∠MJK)
- side lengths are 2√61
Step-by-step explanation:
The given length measures are the diagonals of the rhombus, so each side will be the hypotenuse of the triangle with legs half as long:
√(12² +10²) = √244 = 2√61 ≈ 15.62 . . . . side length
__
The given angle measure is half the measure at ∠J. The full measure of ∠J is 100°, so the measure of ∠K is 180° -100° = 80°

The image is missing so i have attached it.
Answer:
Volume = 1.5 litres
Step-by-step explanation:
Using pythagoras theorem, we can get the height (h) of the cylinder
14² + h² = 17²
h² = 289 - 196
h = √93
Now, volume of a cylinder is;
V = πr²h
In the image, r = diameter/2 = 14/2 = 7cm
Thus,
V = π × 7² × √93
V = 1485 cm³
Now, 1 litre = 1000 cm³
Thus, volume = 1485/1000 = 1.485 litres ≈ 1.5 litres
