Answer:

Step-by-step explanation:

The sum of the angles of a triangle add to 180

40+ 3x+10 + 2x+20 = 180

Combine like terms

70 + 5x = 180

Subtract 70

70+5x-70 =180-70

5x = 110

Divide by 5

5x/5 = 110/5

x = 22

We want to find BCA

BCA = 3x+10

= 3(22)+10

= 66+10

=76

Anna35 [415]

If you multiply 48cm times 15cm,you get 720cm.Which would leave you with 60 left because 780 minus 720 equals 60.The height of the other base is 60cm.
