Answer:

x = 27

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the given angles and equate to 180

90 + x + 23 + x + 13 = 180, that is

126 + 2x = 180 ( subtract 126 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27

How do I solve this?
Kryger [21]
     y = abˣ
   20 = ab¹
   20 = ab
    b      b
20/b = a

 y = abˣ
 4 = (20/b)b²
 4 = 20b
20    20
¹/₅ = b

   y = abˣ
 20 = ¹/₅b¹
 20 = ¹/₅b
  ¹/₅     ¹/₅
100 = b

y = abˣ
y = 100(0.2)ˣ
