Answer:
where are the answer choices
Step-by-step explanation:
Cool question (Although it is tough somewhat)
1st step is to visualize the change from C to C'
we have C'(8,-3) and C(3,-8) supposedly for C because it doesn't show any real values.. Nonetheless
from C to C' there has been a rotation of 90 degrees clockwise
proof:
Clockwise 90 degrees rotation law : (x,y) --> (y,-x) and it proves the change from C to C'
Therefor
all left to do is estimate the B point coordinates and implement the law of rotation
B(8,-7) Now implement a rotation of 90 degrees clockwise
we would get
B'(7,-8)
Hope that helps
Answer:
1
Step-by-step explanation:
all numbers have the multiple of 1 so the least common multiple is 1, you dont have to write that meany down.
Answer:
62
Step-by-step explanation:
step 1: find the height of half the yellow coloured triangle (right angled triangle). <em><u>remember that the angle formed </u></em><em><u>at </u></em><em><u>the </u></em><em><u>center</u></em><em><u> </u></em><em><u>is always 36° for a pentagon.</u></em>
tan36° = opposite/ adjacent
tan36° = 3/h (h for height)
h × ( tan36°) = 3
h = 3 / tan36°
h = 4.13
step 2: calculate area of the right angled triangle
Area = 1/2 × b × h
= 1/2 × 3 × 4.13
= 6.195
step 3: calculate the area of a Pentagon
a Pentagon can be divided into <u>ten</u> right angled
triangle
6.195 × 10
total area = 61.95
rounded off = 62
