A=hbb/2 hope this helps :)
Step-by-step explanation:
Answer:
area=320m²
Step-by-step explanation:
perimeter=2(l+w)
72=2(l+16)
72/2=l+16
36=l+16
36-16=l
l=20m
area=l*w
=20*16
=320m²
Answer:
66 degrees
Step-by-step explanation:
assuming that the line RN crosses line QO in the mid point, and that from that point to R, and to N, are the same length, then the angles R and N should be the same making angle O the complimentary angle, that would be 66 degrees
Answer:
1 - sin² θ = 1 - ( 1 - cos² θ) = cos² θ
tan x csc x = (sin x / cos x) * 1 / sin x = cos x
Step-by-step explanation:
1 - sin² θ = 1 - ( 1 - cos² θ) = cos² θ
tan x csc x = (sin x / cos x) * 1 / sin x = cos x
