Answer:
74.8 ft÷3.4 inches=264
2.1 in x 264=46.2 inches so the width should be 46.2 inches
(I crossed simplify)
Next cross multiply;
3b = 1
b = 1/3
To check if the statement is true just substitute the value of b in the equation;
3b = 1
3(1/3) = 1
1 = 1
Answer:
m∠8 = 49°
Step-by-step explanation:
∠7 and ∠8 are same-side interior angles.
Remember, same-side interior angles are supplementary. This means that the sum of the angles is 180°.
Let's use the variable 'x' to represent the unknown measure of angle ∠8.

(cancels itself out)


Therefore, the measure of ∠8 is 49°.
