Step-by-step explanation:
tan (0)=sin (0)/cos (0)
cos (0)=sin (0)/tan (0)
= -4/5/4/3
= -3/5
Answer:
length of the third side may be either 3.4 m or 2.8 m.
Step-by-step explanation:
Measure of two sides of a right triangle are 1.4 m and the other side is 3.1 m.
then we have to find the measure of third side.
If the third side of the triangle is its hypotenuse then
(Third side)² = (1.4)² + (3.1)²
Third side = 
= 
= 
= 3.4 m
If the third side is one of the perpendicular sides of the triangle and 3.1 m is hypotenuse, then
(Third side)² + (1.4)² = (3.1)²
(Third side)²= (3.1)² - (1.4)²
Third side = 
= 
= 
= 2.76 m
≈ 2.8 m
Therefore, length of the third side may be either 3.4 m or 2.8 m.
