The statement is expressed algebraically as
(x/43) - 87 = -75
Answer:
x =76.45 degrees
Step-by-step explanation:
72 + 252 – 2(7)(25)cos _x__=242
combine like terms
324-350cosx = 242
subtract 324 from each side
-350x = -82
divide by -350
cos x = -82/-350
cos x = 82/350
take the arccos of each side
arccos (cos x) = arccos (82/350)
x =76.45 degrees
Answer:
y = 13.9
Step-by-step explanation:
It is given that
–5.7 + y = 8.2. -----(1)
Equation (1) is a linear equation in one variable.
LHS consists of a constant and a variable term
RHS consists of only constant term
<u>Find the value of y</u>
Solving the equation
-5.7 + y = 8.2
moving -5.7 to the RHS
y = 8.2 + 5.7
y = 13.9
Therefore the value of y = 13.9
-5.7 + y = 8.2
