Answer:
what is the question
Step-by-step explanation:
Answer:
k = - 4
Step-by-step explanation:
The equation that represents direct proportion is
y = kx ← k is the constant of proportion
To find k use any ordered pair from the table.
Using (2, - 8 ) , then
- 8 = 2k ( divide both sides by 2 )
k = - 4
Answer:
Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
Step-by-step explanation:
Pythagorean Theorem: According to this theorem the result obtained by squaring the value of the hypotenuse of a right angled triangle is equal to the sum of the squares of the values other two sides of the triangle.
Hypotenuse = h
Altitude = l
Base = b
l²+b²=h²
Here 6²=36
9²=81
12²=144
15²=225
From the above it is clear that
81+144=225
⇒9²+12²=15²
Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
