Answer:
Step-by-step explanation:
sin60° =
tan60° =
tan45° = 1
cos45° =
(2sin60°)(3tan60°) - (4tan45°)(2cos45°)
now substitute the values of each trigonometrical angles
Answer:
1,2,4,5,8,10,20,25,40,50,100,125,200,250,500,1000
Step-by-step explanation:
You can use the similarity approach of these two triangles CBD and CAE
as a result:
so:
? = 6x^2 / 10 = 0.6 x^2
and the fact of:
"The
segment connecting the midpoints of two sides of a triangle is parallel to the
third side and equals its half length"
so:BD = 0.5 AE 10 = 0.5 * 2x >>> x= 10
Back to:
? =0.6 x^2 = 0.6 * 10^2 = 0.6 * 100 = 60
AHope that helps
