Answer: The measure of the angles are 72 degrees and 18 degrees Step-by-step explanation: we know that If two angles are complementary, then their sum is equal to 90 degrees Let x -----> the measure of an angle y-----> the measure of he other angle we know that x+y=90 -----> y=90-x -----> equation A x=y+54 ----> equation B substitute equation B in equation A and solve for y y=90-(y+54) y=90-y-54 2y=36 y=18° Find the value of x x=y+54 -----> x=18+54=72° therefore The measure of the angles are 72 degrees and 18 degrees
Apply algebra to the equation to solve for x. You can subtract 0.40 from each side to simplify the expression. Here's what it should look like after applying algebra: x = -0.39
