Answer. Number one i think.
3. you cannot simplify √30
It's a vertical angle. Add the two angles 143+33=176
then divide by 2 , 176÷2=88
the answer is C. 88°
First, make 6 into an improper fraction.
6/1
Now multiply the numerators.
6x3=18
Now, the same with the denominators.
1x5=5
18/5
Now make it into a mixed number.
5x3=15
3 and...
18-15=3
3 and 3/5!!
Hope this helped!
