X = 12
Use the Pythagorean Theorem.
13^2 = 5^2 + x^2
169 = 25 + x^2
Subtract 25 from both sides.
144 = x^2
Take the square root.
12 = x
Answer:
A=78
B=102
C=78
Step-by-step explanation:
A= a and 102 are on a straight line so they add up to 180. 180-102=78. The same goes for C
B= the vertical angle for 102, or the same thing with a and c, just flipped around
Speed of Jordan while driving from his home = 56 mph
After Jordan travels 2 miles then Roman started from his house.
Speed of Roman while driving after leaving home= 60 mph
Let after t hours they meet.
And let they cover the distance =d i.e point at which meet.
After time t distance covered by Jordan= 56 t +2
Roman has to cover the distance to catch Jordan= 60 t
A.T.Q
⇒ 60 t=56 t + 2
⇒4 t=2
⇒t=1/2
So, when d = 56×1/2+2=28+2=30 miles
Roman will catch Jordan.
From the above four solutions ,( C.) d = 56 t ,d = 60 t – 2 , Satisfies the above criteria.
So C is the correct answer.
