Answer:
w = x and ΔABC ~ ΔFED
Step-by-step explanation:
In the picture attached, the question is shown.
From definition:
sin(y°) = opposite/hypotenuse
sin(y°) = EF/DF
From definition:
cos(x°) = adjacent/hypotenuse
cos(x°) = AB/C
But sin(y°) = cos(x°), then:
EF/DF = AB/C
wich means that the triangles are similar. Therefore:
∠x = ∠w
∠z = ∠y
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3x + 2y = 7 into this form
Subtract 3x from both sides
2y = - 3x + 7 ( divide all terms by 2 )
y = - x + ← in slope- intercept form
with y- intercept c = → C
