f = 7
Step-by-step explanation:
7f = 49
Divide each side by 7
f = 7
Answer:

Step-by-step explanation:
In leftmost triangle:
opposite side =y
adjacent=a
now, we can use trig formula

now, we can solve for y

In rightmost triangle:
adjacent=b
opposite=y
a+b=15
b=15-a
now, we can use trig formula

now, we can solve for y

now, we can set them equal
and then we can solve for a




now, we can find b


now, we can use trig formula

now, we can find z

we can simplify it
and we get

The sum is the result of adding two or more numbers.
If one number is 7w and another number is 5, then the sum is
7w+5.
Answer: the algebraic expression for the word phrase the sum of 7w and 5 is 7w+5.
Depends are you finding x or other variables
