Each base angle of an isosceles triangle measures 55 degrees and 30 c. Each of the congruent sides is 10 centimeters long. Estimate the following problems to the nearest tenth.
a. Find the altitude of the triangle.
b. What is the length of the base?
c. Find the area of the triangle.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
