An obtuse triangle has two angles 45 n 18 ,and a third unknown angle theta what's the value of the unknown angle​
zlopas [31]

<u>Answer:</u>

An obtuse triangle has two angles 45 and 18. The value of the unknown angle is 117^{\circ}

<u>Solution:</u>

Given that two angles of an obtuse triangle is 45 and 18.  

Third angle is θ  

We are asked to find the value of third unknown angle theta

According to <em>angle sum property of triangle</em>, sum of three angles of triangle is 180^{\circ}

This means in our case sum of 45, 18 and θ should be 180^{\circ}

\begin{array}{l}{=>45+18+\theta=180} \\ {=>\theta=180-63=117^{\circ}}\end{array}

Hence value of unknown third angle of an obtuse triangle is 117^{\circ}

Step-by-step explanation:

<u>80 g rock displaces water:</u>

  • 75 ml - 30 ml = 45 ml = 45 cm³

<u>Density = mass / volume:</u>

  • d = 80 g / 45 cm³
  • d = 1.78 g/cm³ (rounded)

Your turn: Use the triangle given. What is the value of sin Θ?
LekaFEV [45]
You can eliminate D right away. The sine is NEVER greater than one. That's because the denominator of the fraction is always the hypotenuse. 

The definition of the sine is 
Sin(x) = Opposite / hypotenuse.
Sin(x) = 10/26 = 5/13 The fraction reduces.

The answer is B
Done.
