Answer:

<em>15</em>x^{2}<em> + 7x + 12</em>

Step-by-step explanation:

(6x^2 + 7x + 2) - (-9x^2 - 10)

Flip the sign:

- (-9x^2 - 10) becomes + 9x^2 + 10

Combine like terms:

6x^2 + 7x + 2 + 9x^2 + 10

6x^2 + 9x^2 = 15x^2

2 + 10 = 12

Put it all together:

15x^2 + 7x + 12

Write sin 29 degrees 32 minutes in terms of it cofunction
12345 [234]

Answer:

Sin 29° 32' = Cos 60° 28'

Step-by-step explanation:

Here in this problem, we have to write Sin 29° 32' in terms of its co-function.

We know that co-function of Sin Ф = Cos ( 90° - Ф ).

Therefore, we have to find a complementary angle of 29° 32'.

So, ( 90° - 29° 32' ) = 60° 28'

Therefore, Sin 29° 32' = Cos 60° 28' ( Answer )
