To find the measure of angle 4 (m∠4), we need to use the fact that angles 1 and 2 together form a right angle.
A right angle measures 90 degrees.
Angles 1 and 2 together form a right angle, so m∠1 + m∠2 = 90.
m∠2 is given as 47 degrees, so we can substitute this into the equation.
m∠1 + 47 = 90
Now we can solve for m∠1.
m∠1 = 90 - 47
m∠1 = 43
Therefore, the measure of angle 4 (m∠4) is 43 degrees.
Use the image to answer the question.
