Using the Sine Rule:-
20 /sin 45 = BC / sin 30
BC = 20 sin 30 / sin45
= 20 * 1/2 / 1 / sqrt2
= 20 * 1/2 * sqrt2
= 10 sqrt2 answer
I don't know if it could be the area of a square but x has to be 8.34. (ROUNDED)
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:
.
2x + -11 = k
Reorder the terms:
-11 + 2x = k
Solving
-11 + 2x = k
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '11' to each side of the equation.
-11 + 11 + 2x = 11 + k
Combine like terms: -11 + 11 = 0
0 + 2x = 11 + k
2x = 11 + k
Divide each side by '2'.
x = 5.5 + 0.5k
