Answer:

a=9

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2 + b^2 = c^2

a^2 +40 ^2 = 41^2

a^2 + 1600 = 1681

a^2 = 1681-1600

a^2 = 81

Take the square root of each side

sqrt(a^2) = sqrt(81)

a = 9

Answer:

Step-by-step explanation:

Pythagoras Theorem is used in this case:

a² + b² = c²

a² + 40² = 41²

a² + 1600 = 1681

a² = 1681 - 1600

a² = √81

a = 9

9 is the third answer.

a car reduced its speed in a ratio of 2 to 3 if the final speed was 90 km per hour then what was the original speed.

Licemer1 [7]

Answer:

Orginal Speed is 135

Step-by-step explanation:

The ratio of final speed: original speed is

$\frac{2}{3\\}$

We know that 90 km is it final speed so, we set up a proportion

$\frac{2}{3} =90/x$

$2x=270\\x=135$
