Answer:
x = 47.2
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = opp / hyp
cos x = 17/23
Taking the inverse cos of each side
cos ^-1 ( cos x) = cos ^-1 ( 17/25)
x =47.15635696
To the nearest tenth
x = 47.2
Step-by-step explanation:
F(x)=2x
but x= 4
F(x)= 2(4)
F(x)= 8
1/8 is same as 8
0.125

C
Step-by-step explanation:
None of the others have the correct data like C
Answer:
4
Step-by-step explanation:
Step one:
given data
The design is 12 inches by 9 inches.

The poster is 48 inches by 36 inches

Step two:
divide the dimension of the poster by the dimension of the design to get the scale factor

Hence the scale factor is 4
