A triangle has side lengths 8, 12, and 10. Heron’s formula:
Area StartRoot s (s minus a) (s minus b) (s minus c) EndRoot
Use the triangle pictured to calculate the following measurements. Then, calculate the area rounded to the nearest tenth using Heron’s formula.

Perimeter: p = units
Semiperimeter: s = units
Area: A ≈ square units

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

He ! a group of farmers planned to clean 80 acres of wheat per day to finish the work on schedule. right before the work started, they received a new piece of machinery that them clean 10 more acres per day than originally planned. as a result of increased productivity in the last day before the deadline they only had to clean 30 acres. how many acres of wheat did the group of farmers have to clean?
