Pythagoras theorem ! (a²+b²=c²)
Q1) AC = √4.8²+3.6²
= √36
= 6cm
Q2) AB= √17.55² - 6.75²
= √262.44
= 16.2cm
Q3) BC= √14² - 6²
= √160
= 12.64911
= 12.6 cm (to 3sf)
Step-by-step explanation:
235•0.1=23.5
235•0.01=2.35
876•0.01=87.6
876•0.001=8.76
Answer:
17 inches
Step-by-step explanation:
it's 17 because x² = 15² + 8²
then x² = 225+64 which is x² = 289 so now you have to do the square root on both side x= 289
x= 17
