Question

In AABC, LB = 90°, BC = 5 cm and AC - AB = 1 cm, evaluate 1+sinC/cosC​

Answer 1

Answer:

2

Step-by-step explanation:

A+B+C=180 in right angle triangle

A+90+C=180

A+C=90

THEN A=45,B=45

SO ,

$1 \ + \frac{ \sin(45) }{ \sin(45) }$

$1 \ + \frac{1 \div \sqrt{2} }{1 \div \sqrt{2} }$

then after simplifying the answer we get 2
