A dilation by a scale factor of 5 centered at the origin simply multplies by 5 the coordinates of every point. So, the new coordinates are (-5, -25)
Answer:
172.27 in
Step-by-step explanation:
Apply the Sine Rule
Sine Rule is given as:
c = x = ?
C = 180 - (52 + 48) = 80° (sum of triangle)
b = 130 in.
B = 48°
Plug in the values
Multiply both sides by sin(80)
172.274641 = x
x = 172.27 in. (to 2 decimal places)
Answer=56
87.5%*y=49
.875y=49
____ ___
.875 .875
divide both sides by .875
y=56
