Answer:
111113111114111113 and 111111131111111411111113
Step-by-step explanation:
Here we want to know the next two numbers in the sequence.
The key here is that we shall be placing the same number of digit 1 between each of the digits 3 4 3
We went from a single 1 to triple, so the next will be 5 digit 1 and the next will be 7 digit 1
So the next number after the third will be;
111113111114111113
The next number after this will be;
111111131111111411111113
a x=12
the sum of angles in a triangle is 180
53+39+4+7x=180
96+7x=180
7x=86
x=84/7
x=12
b. sum of angles in a triangle is 180
5x+(6x-5)+75=180
5x+6x-5+75=180
11x+70=180
11x=180-70
11x=110
x=110/11
x=10
that's how to solve it
Answer:
seven and a half
Step-by-step explanation:
Answer:
2.6×10^2
3.6×10^2
Step-by-step explanation:
2.5×103=257.5
257.5= 2.575 × 10^2
257.5= 2.6 × 10^2 ( rounding off)
3.442×104= 357.968
3.442×104= 3.57968 × 10^2
3.442×104= 3.6 × 10^2 (rounding off)
Hope it helps :)
