Answer:
a= 158
b=22
Step-by-step explanation:
First we have to find b in order to find a.
To find b we need to add up the two angles we know the value of and subtract it from 180.
90+68= 158
180-158=22
We know b is 22 because the sum of all angles in a triangle is always 180.
Now that we have b we can find a.
we know that a+b=180 so all we have to do is subtract 22 from 180 to get 158.
Answer:
31 students will be going on the trip.
Step-by-step explanation:
Create an equation.
60x+40x+30x=4030
Combine like terms.
130x=4030
Divide.
x=31
Checking solution...
60(31)+40(31)+30(31)=4030
1860+1240+930=4030
4030=4030
