Step-by-step explanation:
x² - 2x - 48
= (x - 8)(x + 6)
Coefficient of x² is positive, => Happy shape curved upwards
Hence x < -6 or x > 8.
7x12 = 84
So the answer is D.
Answer:
A or D
Step-by-step explanation:
I cant totally remember, but a and d make sense. sorry, I learned about this in 6th
The values of the simplified or solved trigonometric functions that are equal are sin and cos, given that the angles are complementary. From the choices above, the answer would be letter C.
sin 36° = 0.5877
cos 54° = 0.5877
It can also be observed that 36° and 54° will sum up to 90°.
