Imagine the shadow and the building height forms a right angle triangle;
We know the height and the shadow make up the "legs" of the triangle,
a²+b²=c²
(750)²+(111)²=c²
562500+12321=c²
574821=c²
c=√574821
c=758.169 ≈ 758.2 ft
Hope I helped :)
It's (4,2). Can you comment why you're having a struggle with this? I might be able to help you.
Answer:
3/4 x 30 = 90/4
= 22.5 laps per hour
Step-by-step explanation:
We are given angle in standard position as

we know that one complete rotation is 360
so, to find angle between 0 and 360
so, we will add 360 to get co-terminal angle
so, co-terminal angle is

now, we can plug value
co-terminal angle is
