Answer:
they are perpindicular because they intersect at a right angle
Step-by-step explanation:
Since the 90% is 63. divide it by 9. then you would get value of 7. then multiple it by 10.
which is equal to 70. so 100% is 70.
The diagonals of a rectangle are congruent so set them equal to each other to get x = 2x - 7. isolate the variable (0 = x - 7 — x = 7) to get x = 7. the diagonals are seven.
Anything which have their degree as 0 is always equal to 1
=> 5^0=1
Option 3 is the answer..!!
Hope this helps you!!
Good Luck!
