They would both be 52°
explanation: they are complementary angles, meaning they are the same. since a line adds up to 180°, take 128° away from 180° and you get 52°
I think it would be two solutions
Answer:
we should know that :
sin ( a + b ) = sin a * cos b + sin b cos a
For the given equation :
sin (π + q) = sin π * cos q + sin q * cos π
sin π = zero and cos π = -1
∴ sin (π + q) = 0 * cos q + sin q * (-1) = - sin q
<u>Another solution:</u>
The angle (π + q) lies in the third quarter ⇒ (1)
(π + q) and (-q) are supplementary angles ⇒ (2)
From (1) and (2)
sin(π + q) = -sin q
Answer:
-8a=8
Step-by-step explanation:
Remember that the decimal point is pronounced as "and".
To the right of the decimals, we have 100 thousandths.
<em><u>Three and one hundred thousandths</u></em>
