Answer:
68
Step-by-step explanation:
For angle A, 3 is the adjacent leg. 8 is the hypotenuse.
The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.



We know the cosine of angle A equals 0.375. We take the inverse cosine of 0.375 to find the measure of the angle.


Answer:
=9y^2−4
Step-by-step explanation:
3y−2)(3y+2)
=(3y+−2)(3y+2)
=(3y)(3y)+(3y)(2)+(−2)(3y)+(−2)(2)
=9y^2+6y−6y−4
=9y^2−4
Answer:
3 × (2 + 3 + 5)
Step-by-step explanation:
I think it’s C. Because
X ≤ 9and 9 is higher than -7 (sorry if I’m wrong)
