The sum of two numbers is 66. the larger number is 2 more than 3 times the smaller. what are the two numbers?

Montano1993 [528]

The two numbers are 48 and 18.

66 = l + s

l = 2 + 3s

66 = 2 + 3s + s

66 = 2 + 4s

66 - 2 = 64

64 = 4s

64 / 4 = 16

66 = l + 16

66 - 16 = 50

50 - 2 = 48

16 + 2 = 18

66 = 48 + 18

Answer:

x = 34

Step-by-step explanation:

ΔABD and ΔBCD are both isosceles triangles

In ΔABD

AB =AD, hence ∠ABD = ∠ADB ( base angles are equal )

∠ABD = $\frac{180-44}{2}$ = $\frac{136}{2}$ = 68°

∠DBC = 180° - 68° = 112° ( straight angle )

∠BCD = x = $\frac{180-112}{2}$ = $\frac{68}{2}$ = 34
