The measure of the length DC to nearest tenth is 24.1 units
Pythagoras theorem
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
