-7•4x=-28x -7•-7=49. -28x+49=105. subtract 49 from the size -28x=56. Then divide -28 from both sides x=-2
A triangle has a total degrees of 180, so you add 55 and 53 to get 108
then you subtract that from 180 to get 72. 72 is your answer
Answer:
20.3 square feet.
Step-by-step explanation:
We have been given the sides of a garden. We are asked to find the area of garden using Heron's formula.
The area of a triangle with sides a, b and c would be:
, where S is the semi-perimeter of triangle.
Let us find semi-perimeter as:
Substitute given side lengths:
Therefore, the area of the garden would be 20.3 square feet.
