Hi, can someone give me the solution for this: The first angle of a triangle is 10 less than the sum of the other two. The measurement second angle is the average of the first and third angle. Find the measurements of all the 3 angles. tnx in advance
Easy. Three equations and three unknowns. Let x, y and z be the first, second and third angles of the triangle Eq.1: x + y + z = 180 (sum of internal angles of a triangle) Eq.2: x = y + z -10 Eq.3: y = (x + z)/2 Now, solve these three equations together and get the answer (x = 85, y = 60, z = 35). You should learn to do your homeworks yourself lol
To add to Bender's post Equate 1 and 2 ( push the x to one side, and the rest to the other side) you will get y+z = 95, which gives x =85 y +z =95 becomes 85+z/2 +z =95 which gives you z =35 The value of y can then be found out.
Which grade are you in? Was it your home work? your teacher may not impressed if you copy your home work/ assignment from internet.
Is the teacher ever likely to know ? Unless he/she is a member here, and Big Pie's friends know that he uses this particular username
