Quick!!!<br> If the side lengths of a triangle are 23, 16, and 7; what type of triangle is it?
ololo11 [35]
<h3>No it does not form a triangle!~</h3>

Let's prove it by pythogoras theorem,

  • Hypotenuse = 23
  • Base = 7
  • Perpendicular = 16

\bf \: H^{2} =P^{2} +B^{2}

\sf \:  {23}^{2}  =  {16}^{2}  +  {7}^{2}

\sf \: 529 = 256 + 49

\sf \: 529  \cancel= 305

<h3>Hence (Proved) </h3>

How to find y in angle sum theorem
Svetach [21]

Answer:

y = 90°

Step-by-step explanation:

  • 110° is the measure of exterior angle of bigger triangle.

  • -> (x + x) + 70° = 110° (By exterior angle theorem)

  • -> 2x = 110° - 70°

  • -> 2x = 40°

  • -> x = 40°/2

  • -> x = 20°

  • y is the measure of exterior angle of smaller triangle.

  • -> y = x + 70° (By exterior angle theorem)

  • -> y = 20° + 70°

  • -> y = 90°

Remember that both the denominator and the square root function cannot have values less than 0.  So to figure what values can go into each we need to do a little math.  Set both the denominator and the under the radical equal to 0
x + 2 = 0            x - 3 = 0
x = -2                 x = 3

Since they must be those numbers or bigger 3 is the larger of the 2 the final answer is
x >= 3  Type in greater than into the box
