Answer:
24
Step-by-step explanation:
- 3x - 15 = x + 33 [sides opposite congruent angles in a triangle are congruent]
- 2x - 15 = 33 [subtract x from both sides]
- 2x = 48 [add 15 to both sides]
- x = 24 [divide both sides by 2]
- BC = 24 [BC = x]
-4/5=2b
since b is alrteady in the subject of the equation simply divide both side of the equation by the coefficient of b
:. (-4/5)/2= 2b/2
-4/10=b
:. b=-2/10 or -0.4
