Okay so 123-45-67+89=100
That should be the answer
The average driving speed would be 62 because you add 198, 150, and 210 and divide the total by 9.
Hope this helped :)
Answer:
C=20° a=10.8 c= 4.3
Step-by-step explanation:
first we need to find the value of angle C by subtracting the sum of angle A and B from 180°.
to find c and a we need to use sin rule which states that sinB/b=sinA/a=sinC/c respectively
