In my opinion I think Factor B 1764 is a better sophisticated answer for two and three
You can check whether this is true using Pythagoras' Theorem. The Pythagorean Theorem:
a² + b² = c², where c is the hypotenuse of a right triangle.
Let's plug in the given values and check the validity of the statement.
a² + b² = c²
7² + 9² = 11²
49 + 81 = 121
130 = 121
This is false. Thus,
Answer:
False - a triangle with side lengths 7, 9, and 11 is not a right triangle.

Answer:
b=6 1/4
Step-by-step explanation:
just trust me!!
tan (π/6) + sin (5π/3) . cos (- 3π/4)
= tan 30° + sin 300° . cos (- 135°)
= tan 30° + sin (360° - 60°) . cos 135°
= tan 30° + (- sin 60°) . cos (180° - 45°)
= tan 30° + (- sin 60°) . (- cos 45°)
= tan 30° + sin 60° . cos 45°
= (1/3)√3 + (1/2)√3 . (1/2)√2
= (1/3)√3 + (1/4)√6
= (4/12)√3 + (3/12)√6
= (4√3 + 3√6)/12
