A. The angles at the intersection of the two lines can be proven to be congruent and complementary . so they meet at a right angle and the lines are perpendicular.
<u>Step-by-step explanation:</u>
In above question, In order to find whether AB ⊥ CD, Using compass construction & rounder , keep the tip at A and cut arcs at line CD . Follow the same process again with tip at B and cut arcs at line CD . Do this both sides of Line CD i.e. on left side of AB & on right side of AB. Now, join the intersection points of both side arcs which are intersecting each other. Now, to prove both are right angle to each other i.e. AB ⊥ CD , can be done by proving congruent and complementary , so they meet at a right angle and Hence , the lines are perpendicular i.e. AB is inclined to CD at angle of 90°.
Answer:
80
Step-by-step explanation:
2:3
2+3=5
2/5×200=80
well, we know the tree is growing at a rate of 36 feet every 3 years, how many feet is that in 1 year alone? well, simply 36/3 = 12.
so the tree is growing 12 feet per year.
when it was first planted, it was 5 feet tall, and then after every year, we have to add 12 feet subsequently, let's do that
year 1 .......... 5 + 12(1)
year 2 .......... 5 + 12(2)
year 3 .......... 5 + 12(3)
year 4 .......... 5 + 12(4)
year 5 .......... 5 + 12(5)
year 6 .......... 5 + 12(6)
year 7 .......... 5 + 12(7)
year y .......... 5 + 12(y)
