1. in triangle abc , angle a is a right angle and angle b = 45. if ac = 12 feet, what is bc?
2. a triangle has side lengths of 34 in., 20 in., and 47in. is the triangle acute, obtuse, or right?

Suppose that △ opq is isosceles with base qp . suppose also that m ∠ o = (5x + 43) ° and m ∠ q = (3x + 30) ° . find the degree measure of each angle in the triangle.

What is the 12th term of b(n)=-4-2(n-1)

Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.
