Answer:

The third angle of isosceles triangle is 106°   .

Step-by-step explanation:

Given as :

The measures of equal angles of isosceles triangle = 37°

i.e \Theta _1 =  \Theta _2 = 37°

Let The third angle of isosceles triangle =  \Theta _3

Now,

An isosceles triangle is that whose opposite sides are equal and two angles are equal

<u>Now, From the property of Triangle</u>

The sum of all three angles of Triangle = 180°

i.e  \Theta _1 +  \Theta _2 +  \Theta _3 = 180°

∵  \Theta _1 =  \Theta _2 = 37° (given)

So,  37° +  37° +  \Theta _3 = 180°

Or, 74° +  \Theta _3 = 180°

Or,  \Theta _3 = 180° - 74°

∴  \Theta _3 = 106°

So, The third angle of isosceles triangle =  \Theta _3 = 106°

Hence,The third angle of isosceles triangle is 106°   . Answer

Find the quotient of <br><br> -85^2-27n+76 / -17n-19
bagirrra123 [75]
<u><em>Answer:</em></u>
5n-4

<u><em>Explanation:</em></u>
<u>The given expression is:</u>
\frac{-85n^2-27n+76}{-17n-19}

<u>1- Take the negative as a common factor from both the numerator and the denominator. This will give us:</u>
\frac{-(85n^2+27n-76)}{-(17n+19)}

<u>2- Cancel out the negative sign (common factor) from the numerator and denominator. This will give us:</u>
\frac{(85n^2+27n-76)}{(17n+19)}

<u>3- Factor the numerator. This wil give:</u>
\frac{(5n-4)(17n+19)}{(17n+19)}

<u>4- Finally, cancel out the (17n+19) which common in both numerator and denominator. This will give us the final expression:</u>
5n-4

Hope this helps :)
