The angles in matching corners are called <u><em>corresponding angles</em></u>. When the two lines are parallel Corresponding Angles are equal
so
m∠y=50° -----> by corresponding angles
and
The angles that are formed on opposite sides of the transversal and inside the two lines are <u><em>alternate interior angles</em></u>. When the lines are parallel, the alternate interior angles are equal.
The value of the year at the end of 2025 will be given by: A=P(1+r/100)^n where: A=future value P=principle r=rate n=number of terms hence for the data given; p=35000 R=5.5 n=(2025-2017)*2=16 Thus A=35000(1+5.5/100)^16 A=$82, 434. 20
