surface area = (2)(5)(13)+(13)(10)+(12)(10)
Answer:
120 i think
Step-by-step explanation:
Calculate the hypotenuse( h ) using Pythagoras' identity
h =√(4² + 7²) = √(16 + 49) = √65
sinΘ = 4 / √65 ⇒ cscθ = √65 / 4
cosθ = 7/ √65 ⇒ secθ = √65 / 7
tanθ =
⇒ cotθ = 
Answer: 2/2
Step-by-step explanation:
6 x 2/2 =6
Answer:
x = -(3/2)
Step-by-step explanation:
i'm going to assume that the left side is (2/3)x and not 2/(3x). If so let me know and i'll change it.
(2\3)x =-1 (multiply both sides by 3)
2x = -1 (3)
2x = -3 (divide both sides by 2)
x = (-3) / 2
x = -(3/2)
