The diagram shows isosceles triangle ABC. AB= AC=7.5. The height of the triangle is 6cm. Calculate the area of the triangle

22.5 cm

Step-by-step explanation:

Triangle area is (L x W) / 2

7.5 x 6 = 45

45 / 2 = 22.5

they share a side

step-by-step explanation:

this is the fundamental definition of adjacent angles

they:

1) share a vertex

2) share a side.

x=-2

step-by-step explanation:

i began by flipping the problem to give me x= on the left (keeps it clearer for me).   so my problem simply became 10x-3=4x-6.  

1)   subtract 4x from the right side, which equals 0.   you do the same to the left of the equal as the right; therefore, subtract 4x from 10x, leaving 6x on the left.

              10x-3=4x-6   :   4x-4x on the right leaves only the -6        

2)             6x-3= 0-6 :    

                6x+3=   -6

3) divide
