PLEASE HELP (WITH SOLUTION) 1.The base of an isosceles triangle and the altitude drawn from one of the congruent sides are equal to 18cm and 15cm, respectively. find the lenghths of the sides of the triangle. 2. two altitudes of an isosceles triangle are equal to 20cm and 30cm. determine the possible measures of the the base angles of the triangle. Solution 1. let the side be x unit . then according to pythagorus theorem 182-x2/4= 225 so, x=19.89 2.Let base be x unit and two sides be y unit according to pythagorus theorem y2-x2/4=400 x2/4-y2=900 after solving these equations x=32.6 y=11.54.

1.The base of an isosceles triangle and the altitude drawn from one of the congruent sides are
equal to 18cm and 15cm, respectively. find the lenghths of the sides of the triangle.
2. two altitudes of an isosceles triangle are equal to 20cm and 30cm. determine the possible
measures of the the base angles of the triangle.
Solution
1. let the side be x unit .
then according to pythagorus theorem 182-x2/4= 225
so, x=19.89
2.Let base be x unit and two sides be y unit
according to pythagorus theorem
y2-x2/4=400
x2/4-y2=900
after solving these equations x=32.6 y=11.54
