Question

In triangle RST, RT = 12 cm, ST = 12 cm and angle RST = 90 degrees

calculate the length of RS, giving your answer correct to one decimal place.

Answer 1

Explanation:

RS=SQUARD ROOT ((RT) SQUARED+ (ST) SQUARED)

RT =12 SQUARED= 144 ST SQUARED= 144, ADD TOGETHER EQUALS 288.

SQUARE ROOT OFF 288 EQUALS 16.95 RS = 16.9

Answer 2

180 degrees
