The measure of the length DC to nearest tenth is 24.1 units
<h3>Pythagoras theorem</h3>
In order to determine the measure of DC from the figure shown, we will use the pythagoras theorem
Determine the measure of BC
BC² = 22² - 15²
BC² = 259
BC = 16.09
Determine the measure of DC
DC² = 259 + 28²
DC = √583
DC = 24.1 units
Hence the measure of the length DC to nearest tenth is 24.1 units
