document.write( "Question 792097: Hello. I have an assignment but I don't know how to solve some of these word problems (that are algebraic equations by the way) but I already know the answers by guess and check. Okay so \"A family of Isosceles triangles has the property that the two equal angles are each 2/15 of the angle. Find the measure of all 3 angles\" so the equation I think would be 180=x(times) 2/15. the angles are 19,19, and 142 but I don't know how to show it. :) \n" ); document.write( "

The two equal angles (the base angles) are each 2/15 of what angle?
\n" ); document.write( "A straight angle (a \"180%5Eo\" angle)?
\n" ); document.write( "The vertex angle of the isosceles triangle?
\n" ); document.write( "
\n" ); document.write( "OPTION 1:
\n" ); document.write( "If each the base angles measures \"2%2F15\" as much as a straight angle, we do not even need an equation to find the measure of those angles. The measure of each base angle would be
\n" ); document.write( "\"180%5Eo+%2A%282%2F15%29=24%5Eo\".
\n" ); document.write( "Then, if we can call the measure of the remaining angle \"x\".
\n" ); document.write( "\"42%5Eo%2B42%5Eo%2Bx=180%5Eo\"
\n" ); document.write( "\"84%5Eo%2Bx=180%5Eo\"
\n" ); document.write( "\"x=180%5Eo-84%5Eo\"
\n" ); document.write( "\"x=96%5Eo\"
\n" ); document.write( "
\n" ); document.write( "OPTION 2:
\n" ); document.write( "If each the base angles measures \"2%2F15\" as much as the vertex angle, the measures are not going to be whole numbers.
\n" ); document.write( "
\n" ); document.write( "\"x\"= measure of the vertex angle of the isosceles triangle (in degrees)
\n" ); document.write( "
\n" ); document.write( "The summ of the measures of the angles in any triangle is \"180%5Eo\", so
\n" ); document.write( "\"%282%2F15%29x%2B%282%2F15%29x%2Bx=180\" is our equation.
\n" ); document.write( "
\n" ); document.write( "Simplifying and solving:
\n" ); document.write( "\"%282%2F15%29x%2B%282%2F15%29x%2Bx=180\"
\n" ); document.write( "\"%282%2F15%29x%2B%282%2F15%29x%2B1%2Ax=180\"
\n" ); document.write( "\"%282%2F15%2B2%2F15%2B1%29x=180\"
\n" ); document.write( "\"%282%2F15%2B2%2F15%2B15%2F15%29x=180\"
\n" ); document.write( "\"%28%282%2B2%2B15%29%2F15%29x=180\"
\n" ); document.write( "\"%2819%2F15%29x=180\"
\n" ); document.write( "Multiplying times 15 both sides of the equal sign, we get
\n" ); document.write( "\"19x=180%2A15\"
\n" ); document.write( "\"19x=2700\"
\n" ); document.write( "\"x=2700%2F19\" (about \"142.1%5Eo\")
\n" ); document.write( "Then, each of the other two angles would measure
\n" ); document.write( "\"%282%2F15%29%282700%2F19%29=2%2A2700%2F%2815%2A19%29=36%2F19\" (about \"18.95%5Eo\")
