Yes because 0 and 4 dont equal 10 and 20 and 40 dont equal 100. So no and 40 + 23 = 63.

Yes because when you add, there's nothing to carry. 23 plus 40 equals 63.

Find tan , sin , and seco, where 0 is the angle shown in the figure.
kicyunya [14]

Answer:

  • tan(θ) = 5/3
  • sin(θ) = 5√34/34
  • sec(θ) = √34/3

Step-by-step explanation:

The hypotenuse is given by the Pythagorean theorem:

  h = √(3² +5²) = √34

The trig functions are the ratios of sides:

  Tan = Opposite/Adjacent

  tan(θ) = 5/3

__

  Sin = Opposite/Hypotenuse

  sin(θ) = 5/√34 = (5/34)√34

__

  Sec = Hypotenuse/Adjacent

  sec(θ) = √34/3

Could 7.7 cm, 4.0 cm, and 1.7 cm be the side lengths of a triangle?
Sedbober [7]
  • Triangle Inequality Theorem: States that the sum of any two sides of a triangle is greater than the length of the third side; A+B>C\\B+C>A\\A+C>B

So for this, we are applying the triangle inequality theorem. If any of the inequalities are not true, then this cannot be a triangle. (Let A = 7.7, B = 4.0, and C = 1.7)

7.7+4.0>1.7\\11.7>1.7\ \textsf{(true)}\\\\4.0+1.7>7.7\\5.7>7.7\ \textsf{(false)}\\\\7.7+1.7>4.0\\9.4>4.0\ \textsf{(true)}

<u>Since the second inequality is false, these lengths cannot form a triangle.</u>
