Answer:
45/28
Step-by-step explanation:
Hey There!
They want us to find the tangent of R
Remember in sohcahTOA
t - tangent
o - opposite
a - adjacent
meaning that

The opposite of angle r is 45
the adjacent of angle r is 28
so 
3/4(1/2x + 4) + 1/2(x − 1)
First use distributive property to remove the parentheses:
3/8x + 3 + 1/2x -1/2
Now combine like terms:
7/8x + 2 1/2
