Answer: the root of 145 so b
Step-by-step explanation:
None of these answer choices are correct. The answer would be 51. 52+53=105
105-54=51
Answer: B. No
Step-by-step explanation:
Direct variation has the following form:

Where the constant of variation is "k".
By definition, in direct variation, when the variable "x" changes, tha variable "y" changes in proportion to the variable "x".
As you can observe in the table, when the value of the variable "x" increase, the values of the variable "y" decrease, therefore we can conclude that it is not a direct variation.
Then the answer is the option B.
Remember that tif the legs of a right tirsnalge are a and b and they hypoonuse is c then
a²+b²=c²
so
we also know that the area of a triangle is 1/2bh
we are given that area=60 and base=8
so
60=1/2 times 8 times height
60=4 times height
divide both sides by 4
15=height
so the legs are 15 and 8
a=15
b=8
15²+8²=c²
225+64=c²
289=c²
sqrt both sides
17=c
the hypoonuse is 17ft
