Answer:
42*
Step-by-step explanation:
Each triangle's angles in sum give 180 degrees. From here we add 68 and 70 to get 138, then subtract 138 from 180 to get 42, and that would be the third angle.
Tell me if I'm wrong :)
Step-by-step explanation:
no it is not because if 3 maps on 2, then it cannot map on -2 at the same time

Answer:
120 minutes
Step-by-step explanation:
large horse + small horse = together
1 pool/40 minutes + x = 1pool/30 minutes
1/40 + x = 1/30
subtract 1/40 from both sides
x = 1/30 - 1/40
use 120 as common denominator
x = 4/120 - 3/120
x = 1/120
x = 1 pool / 120 minutes
It takes the small horse 120 minutes
Answer:
steps
Step-by-step explanation:
(1 + sinx)(1 - sinx) = 1 - sin²x = cos²x or = cos² -x
cos -x = cos x
∴ (1 + sinx)(1 - sinx) will not equal cos -x, unless x = ±360° or 0°
where cos ±360° or cos 0° = 1
