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.
b is 22° and a is 158°
b can be calculated by angle sum property and a can be calculated using exterior angle sun property

Step-by-step explanationbfd:
18
because 20% of 90 is 18
