Answer:
Option D (180°-m∠2)
Step-by-step explanation:
we know that
m∠1+m∠2=180° ------> equation A (by supplementary angles)
m∠3+m∠2=180° ------> equation B (by supplementary angles)
m∠1=m∠3 -----> equation C (by vertical angles)
Solve for m∠1 in equation A
m∠1=180°-m∠2
Remember that
m∠1=m∠3
so
m∠3=180°-m∠2
therefore
m∠1=180°-m∠2
m∠3=180°-m∠2
The expression that represent the measure of both angle 1 and angle 3 is
(180°-m∠2)
Answer:
D
Step-by-step explanation:
If it is half the distance, it would be divided by 2. plus 5 miles more would be added after the division.
Answer:
The arrow is at a height of 500 feet at time t = 2.35 seconds.
Step-by-step explanation:
It is given that,
An arrow is shot vertically upward at a rate of 250 ft/s, v₀ = 250 ft/s
The projectile formula is given by :
We need to find the time(s), in seconds, the arrow is at a height of 500 ft.
So,
On solving the above quadratic equation, we get the value of t as, t = 2.35 seconds
So, the arrow is at a height of 500 feet at time t = 2.35 seconds. Hence, this is the required solution.
Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36
Since the number is prime, the last digit can only be 1 or 9.
Possible numbers are 419, 941, 661
Therefore, Andrea's mystry number is 941
