CPCTC<span> is an acronym for corresponding parts of congruent triangles are congruent. </span>CPCTC<span> is commonly used at or near the end of a proof which asks the student to show that two angles or two sides are congruent.</span>
Answer:
a.
2x+4x+3x=180 sum of interior angle of the triangle is 180
9x=180
x=180/9=20
b.
x-20+x+10+x-20=180sum of interior angle of the triangle is 180
3x-30=180
3x=180+30
x=210/3=70
c.x+10+x+20+x=180 linear pair
3x+30=180
3x=180-30
x=150/3=50
Let the width be x, then the length is x + 10.
Area = length x width = x(x + 10) = 200
Solving the quadratic equation, we have that
x = 10 feet
i.e. the width is 10 feet.
