Find the measure of the missing angle. a= _

(NO FILES) IF YOU ANSWER YOU WILL BE MARKED BRAINLIEST :)

a= 32

Step-by-step explanation:

Since "a" is a part of a supplementary angle (An angle that adds up to 180º)

What you would need to do is add 58º and 90º (90º because the right angle = 90)

so 58+90 = 148

Then you would subtract 148 from the total of the angle (Which is 180)

so 180 - 148 = 32, And that shows that a = 32
