Answer:
-76
Step-by-step explanation:
A positive digit multiplied by a negative digit will result as a negative digit.
So,
6 · -8 = -48
Now if there is a problem where a number is added by a negative digit number, you turn the "plus" sign into a "negative" sign.
So,
- 48 + (- 28)
-48 - 28
If you subtract a negative by a negative, the answer will be negative BUT you have to ADD those two negative digits together and put the negative sign after.
- 48 - 28 = -76
Answer:
A = 40.0 (3 sig. fig)
C = 40
c = 15
Step-by-step explanation:
Using sin law,
sinA/15 = sin100/23
A = 40.0 (3 sig. fig)
Using angle sum of triange,
C = 180 - 40.0 - 100 = 40
Since angleA = angleC, by side equal opp angles, c = 15
Divide 2106 by 27 = 78
78 is the answer
