Answer:
38
Step-by-step explanation:
we are given
number of cubes in bottom is 3*16=18
we can see that
number of layers is 8
now, we can find total number of cubes
total number of cubes = number of layers*number of cubes in bottom
so, we get
total number of cubes = 8*18
total number of cubes is 144
so, option-C..........Answer
Answer:
2b + 42 = 134 —> Opposite angles
2b= 134 – 42
2b= 92
b= 92/2
<h3>b= 46</h3>
(2b+42) = 2(46)+42 = 92 +42= 134°
134 + (3a+4) =180
134+3a+4=180
3a+138=180
3a= 180 – 138
3a = 42
a=42/3
<h3>a=13</h3>
I hope I helped you^_^
