Yes, both fractions are equal.
Answer:
x = 16
y = 20
Step-by-step explanation:
the left part of the triangle can be solved first as it already has one angle and 1 side, we use trigonometry for this.
since we have 2 sides and 1 angle, to find the third side length we use the pythagoras theorem. a² + b² = c²
; 9² + 12² = c²
; 225 = c²
;√225 = c
; 15 = c
since we have all the lengths of the triangle, we can find out the angle opposite to the side length '9',
;
;
x 9 = Sinx
36.86 = x
now, we look at the triangle as a whole, the top angle being 90 degrees, we know that we have 36.86.
; 90 - 36.86 = 53.13

;
x Sin 90 = 20
y = 20
again, since we have 2 sides of a right angled triangle we use a² + b² = c²
we arrange this formula since we have the hypotenuse
; 20² - 12² = 256
; √256 = x
; 16 = x

Answer:
See below.
Step-by-step explanation:
The slope of the line is (5-1) / (3 - -3)
= 4/6 = 2/3
Point slope form:
y - y1 = m(x - x1)
Plugging in m = 2/3 and the point (-3,1):-
y - 1 = 2/3(x + 3) (answer)
Slope-intercept form:-
y - 1 = 2/3(x + 3)
y = 2/3x + 2 + 1
y = 2/3x + 3 (answer)
Standard Form:-
y = 2/3x + 3
Multiply through by 3:-
3y = 2x + 9
-2x + 3y = 9 (answer).
