Step-by-step explanation:
what is the main condition the lengths of the sides of a right-angled triangle have to fulfill ?
Pythagoras !
c² = a² + b²
c is the Hypotenuse (the baseline opposite of the 90 degree angle), a and b are the so-called legs (the sides enclosing the 90 degree angle).
only if there is a combination of the sides, for which the Pythagoras equation is true, do we have a right-angled triangle. otherwise not.
we also know CA = 18 - 7 - 3 = 8 cm
so, let's try
8² = 7² + 3²
64 = 49 + 9 = 58 wrong
7² = 8² + 3²
49 = 64 + 9 = 73 wrong
3² = 8² + 7²
9 = 64 + 49 = 113 wrong
so, there is no combination, where the Pythagoras equation is true, so it is NOT a right-angled triangle.

Step-by-step explanation:
The area of the parallelogram using area of rectangle and area of two triangles is 84 m²
<h3>How to find area of a parallelogram</h3>
- Area of a rectangle = length × width
= 8m × 7m
= 56 m²
- Area of each triangle = 1/2 × base × height
= 1/2 × 4m × 7m
= 1/2 × 28
= 14m²
- Total area of triangles = 2(14 m²)
= 28 m²
- Area of parallelogram = area of rectangle + area of two triangles
= 56 m² + 28 m²
= 84 m²

Answer:
Step-by-step explanation:
Let P be price after t year . From the formula of compounding
P = 9 
Taking log to the base e on both sides
ln P = ln 9 + t ln 1.015
= (2.197 + .0149t )
P =
