Answer:
D is the right one
Step-by-step explanation:
π radian = 180 degree
-> 135 degree = π radian
-> 135 degree = 0.75 * π radians = 3π/4 radian
Answer:
Answer = 93.6
Step-by-step explanation:
frist multipy 9 x 13 to get 117 than divided it by 2 = 58.5, than times it by 3 since there is three sides.
(58.5 x 3 is 175.5)
Than for the base multipy 7.8 x 9 = 70.2, but since its a tri, divided it by 2 = 35.1.
Add 58.5 and 35.1 to get 93.6
49=-7k is equivalent to D because when you simplify both of them, you get -7=k
C if its a question on plato
