Question

Sum of half of Right angle and half of a straight angle is?

Answer 1

Answer:

I think 180 degree

I think 180 degree

Answer 2

Answer:

Required sum is 135°.

Step-by-step explanation:

Here we have Right angle and Straight angle.

We want to find sum of these two angles.

We know value of Right angle $= {90}^{o}$

and value of Straight angle $= {180}^{o}$

So half of Right angle = 45°

and half of Straight angle = 90°

Now sum of half of Right angle and half of Straight angle

$= {45}^{o} + {90}^{o} \\ = {135}^{o}$

Some important Mathematics formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
