Answer:
see explanation
Step-by-step explanation:
Using the double angle identity for sine
sin2x = 2sinxcosx
Consider left side
cos20°cos40°cos80°
= 
(2sin20°cos20°)cos40°cos80°
= 
(2sin40°cos40°)cos80°
= (sin80°cos80° )
= 
(2sin80°cos80° )
= . sin160°
= . sin(180 - 20)°
= . sin20°
= 
= right side , thus proven
A= 2 WL+ 2 LH+ 2 HW.
W= width
L= length
H= height
Answer:
Look down
Step-by-step explanation:
So, to use distributive property you have to multiply the out side to the inside.
3(9-4)=15-8
Multiply 3and nine then 4.
3+27-12=15-8
I hope this helped you
ANSWER
y = 2/3x + 15
Explanation:
Equation used: y - y1 = m( x - x1 )
y - 9 = 2/3 ( x - -9 )
y - 9 = 2/3x + 6 ( distribution )
y - 9 = 2/3x + 6 ( add 9 to 6 )
y = 2/3x + 15
The last statement : Line segments E'F' and G'H' do not intersect and are the same distance apart as EF and GH, is the correct answer. A translation is simply a transformation in which all the point of a figure move the same distance in the same direction. So the points will not intersect.
