This was kinda like Science
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.
In radians this are

To find the complement of 3π/4, subtract it by π/2

To find the supplement of 3π/4, subtract it by π.
Step-by-step explanation:
1kg of grapes = $1.50
=> 3.5kg of grapes = $1.50 * 3.5 = $5.25
1kg of carrots = $1.00
=> 2.25kg of carrots = $1.00 * 2.25 = $2.25
Total cost = $5.25 + $2.25 = $7.50.
2x-2-3x3 =-13. -13 is the answer
B is correct. 30+95=125. 180-125=55 degrees. Hope this helps! ;)
