10•3^2x = 6•5^x+1 it’s a math problem why do i have to write 20 characters

The triangles in the diagram are congruent. if mzf = 40°, mza = 80°, and mzg = 60°, what is mzb?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.

Find the length of the normal and the angle it makes with the positive x-axis. (see pictured below)
