Answer:
The answer is in pictures.
hope it helps:)
A single angle is generally not considered to be supplementary. Supplementary angles are angles that equal 180° when they are added together. For example, 70° and 110° are supplementary because they equal 180°.
However, I guess the supplementary angle can be the angle that must be added to another to total 180°. For example, 80° is the supplementary angle of 100°.
The statement given is :
If a figure has three sides , it is a triangle
contrapositive statement is :
If a figure is not a triangle, then it does not have three sides.
last option is correct
Answer:
BC= 1.92837
Step-by-step explanation:
sin40=0.64279
or,perpendicular(BC)<em>/</em>hypotenuse(AB)=0.64279
or,BC/AB=0.64279
or,BC/3=0.64279
or,BC=0.64279 x 3
:.BC=1.92837 <u>ans</u>
