Step-by-step explanation:
0+1 = 1
1/2+1/2= 1
-50 + 51= 1
Answer:
-21=24
Step-by-step explanation:
Subtract 24 from 3
-21=8+2^2
Raise 4 to the power of 2
-21=8+16
Add 8 and 16
-21=24
Sine (28) = opposite / hypotenuse =
0.46947 = opposite / 28
opposite = 0.46947 * 28

</span>
</span>
</span>
cosine (28) = adjacent / hypotenuse =
0.88295 = adjacent / 28
adjacent = 28 * .88295
<span><span><span>adjacent side = 24.7226
