What are the similar triangles?

What is the measure of the smallest angle in the diagram? 15 29 32 45

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29
