Which option shows the measure of the unknown angle, x and how to find it

E) 37

Step-by-step explanation:

The total measurement for the angle ABC is 90 as it is a right angle.

Add your known angles together and substract from 90 to get your unknown.

90 - 21 - 32 = 37

E. Subtract 21 and 32 from 90, x=37

Step-by-step explanation:

Since there are 90 degrees in a right angle, we can find the missing angle by adding the two angles we have together and then subtracting the sum from 90.

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
