Answer:

113°

Explanation:

Calculate the angle of the minute hand (θm)

The clock face is a circle of 360°, and there are 60 min in 1h,

so, the minute hand travels 6° in 1 min.

In 26 min, the minute hand will travel

θm = 26 × 6

= 156°

Calculate the angle of the hour hand (θh)

The hour hand travels 360° in 12 h, so it travels 30° in 1 h

It has travelled for 1 h 26 min = 1²⁶/₆₀ h.

θh = 1²⁶/₆₀ × 30

= 86/60 × 30

= 43°

Calculate the angle between the hands

θ = θm - θh

= 156 - 43

= 113°

The angle between the hands is 113°.
