Answer:
x = 129°
Step-by-step explanation:
∠ ABD and ∠ DBC are a linear pair and sum to 180° , then
y + ∠ DBC = 180°
107° + ∠ DBC = 180° ( subtract 107° from both sides )
∠ DBC = 73°
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles , then
x = ∠ DBC + z = 73° + 56° = 129°
5x-3=2.5x+x solve this equation that I just gave you for X then plug it in to 2.5x and that will equal MN
Well, since you have two variables in one equation, you would have to have at least one other equation to solve this problem. Their isn't enough information to solve this alone, sorry :/
Hi there! The answer is 56 + 8x square feet
The length of a rectangle is 8 feet.
The width of that rectangle is 7 + x feet.
We can find the area of the rectangle by using the formula A = L x W
(Area = Length x Width)
Filling in this formula gives us:
A = 8 (7 + x) = 56 + 8x square feet
4 dollars and seventy six cents will be the total
