First subtract 2 revolutions from the - 840 :- (- (840-720) = -120
This gives sin -120 which is in the 3rd quadrant of the unit circle
sin -120 = - sin 60 = - sqrt3/2
Answer:
2 terms
Step-by-step explanation:
The smaller triangle is 1/6 the size of the large one ( 5/30 = 1/
Area is squared 1/6 ^2 = 1/36
Multiply the area of the large triangle by 1/36:
270 x 1/36 = 270 /36 = 7.5
The area is 7.5 cm^2
The answer is A.
Answer:
.
Step-by-step explanation:
Start by finding the slope of this line.
If a slanting line goes through 
and 
, where 
, the slope of this line would be:
.
The line in this question goes through 
and 
. Hence, the slope of this line would be:
.
If a slanting line with a slope of 
and goes through the point , the equation of this line in the point-slope form would be:
.
For the line in this question, the slope is 
. Take as the chosen point on this line. The point-slope form equation of this line would be:
.
Rewrite to obtain the equation of this line in the slope-intercept form:
.
