Mike had $12. he bought a book for $4 and a record for $5. how much did he spend ?

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.

Solve the triangle. a = 21°, c = 105°, c = 5

With alll of except for the 2 that i did already
