we know that
90°+∠BAC=180°------> by supplementary angles
∠BAC=90°
125°+∠ABC=180° -----> by supplementary angles
∠ABC=55°
∠BAC+∠ABC+p=180----> <span>sum of the internal angles of a triangle is 180 degrees
</span>p=180-90-55-----> p=35°
the answer is
p=35°

Answer:
Speed of river's current = 5 mph
Step-by-step explanation:
Let 'd' be the distance covered
Let x be the speed of the rivers current
Speed upstream = 15-x
speed downstream = 15+x
Time = distance / speed
time upstream =
time downstream =
the ferry trip upstream takes twice as long as its return trip downstream
=
divide both sides by d
=
cross multiply
Add 2x on both sideds
subtract 15 from both sides and divide by 3
x=5
Speed of river's current = 5 mph
Answer:
Total temperature change 104.25 f.
Step-by-step explanation:
Average temperature change is calculated by dividing total temperature change by the total hours it took for the change.
We have been given the average temperature change.
We have to multiply average temperature change by the total number of hours it took for the temperature to change we get the total temperature change.
⇒ Total temperature change = Average temperature change * total hours
=
=104.25 f
