The opposite angle is also 80°. since consecutive angles must total 180, the other 2 angles are 100 each. 100+100+80+80=360, as needed for a parallelogram
3 x3 = 9 4 x 3 =12 6 x 2 = 18 3 x
1c+4s=112
1c=3s
3s+4s=112
7s=112

Expression consists of numbers, variables, and mathematical operations. The expression f(w)=5(w+4) is equal to f(9)=5(9)+20.
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The expression is given to you is,

Now, if we solve the expression it can be written as,

substituting the value of w, we will get,

Hence, the expression f(w)=5(w+4) is equal to f(9)=5(9)+20.
