X/-3 = 12 + x
x = -36 - 3x
4x = 36
x= = 9
The number is 9.
Answer:
Cos 74°= Sin 16°
Sin 20°= Cos 70°
Sin A°=Cos (90°- A°)
Step-by-step explanation:
This is because the three pairs are complementary i.e they add up to 90° and in trigonometric ratios, complementary ratios are equal.
You can do a notebook a door , a frame or a mirror, mostly anything that has angles
I assume you mean -5 and 3/4 instead of -53/4. In that case, it cannot be A, as -5.8 is less than -5.75 (AKA -5 3/4). It cannot be C or D either, though, as the number has to be less than -5.5, and -5.4 or -5.3 are both more than -5.5. Thus, by process of elimination, it has to be B, - 5.7. Hope I helped! Good luck in future!
Answer:
20
Step-by-step explanation:
If each space has an area of 5, we just have to multiply by 4 since there are 4 spaces.
4(5)=20
