Question

find the measure of the missing angle.
26°
a

Explanation:

Step1: Identify the angle type

The diagram shows a right angle (90°) split into two angles: 26° and \( a \).

Step2: Use angle addition for right angle

In a right angle, the sum of the two smaller angles is 90°. So, \( 26^\circ + a = 90^\circ \).

Step3: Solve for \( a \)

Subtract 26° from both sides: \( a = 90^\circ - 26^\circ = 64^\circ \).

Answer:

\( 64^\circ \)
