Answer:
answer 90
Step-by-step explanation:
since the sum of the external angles
triangle is 180
internal equal to 90
The minute hand when moving is swiping a sector
The arc length is given 23.5 inch the angle swiped is 52 degree
we have to find radius
length of arc = 2pi r( theta )/360
23.5 = 2* 3.14 * r ( 52/360)
23.5 = r(0.907)
r= 23.5/ 0.907
r=25.90 inches Answer
Answer:
Height of tree 3 years ago: 24 inches
Height of tree now: 54 inches
