Question

The total measure of two adjacent angles is 153°. If one of the adjacent angles measures 104.7°, determine the measure of the other adjacent angle.

a. 194.7°
b. 257.7°
c. 48.3°
d. 75.3°

Answer 1

By subtracting the given angle measurement, 104.7°, from the total measurement, 153°, we find that the measure of the second adjacent angle is 48.3°.

Step-by-step explanation:

To find the measure of the second adjacent angle when the total measure of two adjacent angles is known, you can use the following steps:

1. Subtract the measure of the known angle from the total measure of the two angles. In this case, subtract 104.7° from 153°.
2. The result is the measure of the other adjacent angle.

So, the calculation will look like this:

153° - 104.7° = 48.3°

Therefore, the measure of the other adjacent angle is 48.3°, which corresponds to answer option (c).
