17) The product of two rational numbers is 52. If one of the numbers is $\frac{13}{14}$, find the
other.
18) Divide $-22x^3y^6z^3 - 44x^4yz^4 + 11 x^2y^2z^2$ by $x^3y^3z^4$.
19) Find unknown angles in the figures below:
B
55°
75°
AB = AC
C
B
50°
BD = DC = AD
C
20) The ratio between a base angle and the vertex angle of an isosceles triangle is 2:3. Find
each angle of the triangle.
