The unlabeled part of the right angle is complementary to 68 degrees, so 22 degrees. y is supplementary to 78 degrees, so 102 degrees. z as the third angle in the small triangle is 180 less than the sum of the other two,
z = 180 - 22 - 102
Answer: 56 degrees
5^3(5^x) the rule is a^b(a^c)=a^(b+c)
5^(3+x)
W-5=5
W= 5+5 (bringing -5 to the other side, it becomes +5)
At last, W=10.
