Answer:
A cos C = 12/13
Step-by-step explanation:
cos theta = adjacent side/ hypotenuse
cos C = BC/AC
But we don't know BC, but we can find it using the Pythagorean theorem
a^2 +b^2 = c^2
5^2 +BC^2 = 13^2
25 + BC ^2 =169
Subtract 25 from each side
BC^2 = 169-25
BC ^2 = 144
Taking the square root of each side
BC =12
cos C = 12/13
Answer:
156 is the answer
Step-by-step explanation:
this is the same as saying 36 divided by 3 times 13.
the difference between 15 and 2 is the same as saying 15-2
Answer:
Step-1 : Multiply the coefficient of the first term by the constant
Step-by-step explanation:
Expression 3,
because 6 and 8 are factors of 48. Since positive 6 & 8 are the two numbers of choice, the product will be positive. My answer is reasonable because if you were to multiply positive 8 and 6 you will get positive 48.
False: although the size increases to its ratio, it is not considered similar
