Question

Tolong pliiis pake cara yaa!

Answer 1

3. sudut KLM ( Sudut tumpul)

4. sudut B = 90 - 25 = 65

5. sudut kecil = 5/12 X 180 = 75

6.  180 - 116 = 4x + 8x + 4
      64          = 12x + 4
      64 -4     = 12x
       60/12   = X = 5

7. x = 180-90-50 = 40
   z = x = 40
   y = 180-40= 140
x + y + z = 40 + 40 + 140 = 220

8. 5x + 100 = 9x
      100 = 9x-5x
      100/4 = x = 25
9. <CBA = 180 - 135 = 45
    < ACB = 180 - CBA - BAC
                =  180 - 45- 60 = 75

10. 8a = 128
        a= 128/8 = 16
  
     4d = 180-128
        d = 52/4 = 13 
    
5b + 12 = 52
5b = 52-12
b= 40/5 =8

5c - 13 = 52
5c =52 +13
c = 65/5 = 13
