The vertex angle of an isosceles triangle measures 42°. A base angle in the triangle has a measure given by (2x + 3)°. What is t
larisa [96]

An isosceles triangle is one in which 2 angles have similar measure while the other one is different. In this case, the 2 vertex angles have a measure of 42 degrees, therefore the third angle which is equal to (2x + 3) is:

(2x + 3) + 42 + 42 = 180

2x + 3 = 96

I am so stuck! :( Pls help me!!! I don't get the problem and I don't know how to solve it
Lelu [443]

Answer:

\frac{n^{2}}{2a}

Step-by-step explanation:

  • Just split it up first \frac{9an^{3}}{18a^{2}n}=\frac{9}{18}\times \frac{a}{a^2} \times\frac{n^3}{n}
  • Then 9 divided by 18 can be simplified into the fraction 1/2
  • What can go into a and a^2 ? a itself right, so if you divide a by a you get 1, if you divide a^2 by a you get a
  • Same as the a fraction, if you divide n^3 by n you get n^2
  • \frac{9an^{3}}{18a^{2}n}=\frac{9}{18}\times \frac{a}{a^2} \times\frac{n^3}{n}=\frac{1}{2}\times \frac{1}{a} \times\frac{n^2}{1}=\frac{n^{2}}{2a}
