Answer:
B. m∠RTS = 78°
Step-by-step explanation:
The sides GH and GI of ΔGHI have the same length, so their opposite angles, ∠I and ∠H will have the same measures. Call that measure "x".
The sum of angles in a triangle is 180°, so we have ...
24° +x +x = 180°
2x = 156° . . . . subtract 24°
x = 78° . . . . . . divide by 2
The triangle similarity statement tells you that ∠T will have the same measure as ∠I, which is x, or 78°.
m∠RTS = 78°
That's easy
the y intercept is where it hits the y axis
that is how far up or down
so then it tells you to transform it 3 units down
just find the y intercept then minus 3 from it
ok
y intercept is where line crosses y axis or where x=0
so set x=0 and solve for y
6(0)+5y=-15
0+5y=-15
5y=-15
y=3 is the y intercept
translate 3 units down so
3-3=0
y=0 is the y intercept after transformation (should be translation)
