Here is the work and the answer (D=7
Answer:
Option (b) is the answer.
Step-by-step explanation:
If two distinct lines intersect
Then they are not parallel because parallel lines never intersect they go hand in hand
But since, we need to tell which is not true
So, option A is discarded.
Option (c) and (d) are also true hence, discarded.
Option (b) is correct that is the lines are perpendicular this is not true. hence, considered
Therefore, option (b) is the answer.
Answer:
a=8
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 +15^2 = 17^2
a^2 +225 = 289
Subtract 225 from each side
a^2 +225-225=289-225
a^2 = 64
Take the square root of each side
sqrt(a^2) = sqrt(64)
a = 8
