Answer:
A) 3a = 180°
B) a+ 55° + 36° = 180°
C) x + y + z = 180°
Step-by-step explanation:
The answer is the A option since all the side of the triangle could be the same, making it an equilateral triangle. ( 60° + 60° + 60° = 180° )
The sum means that all the angles are added, not necessarily being similar terms, which equals to 180°.
The terms don't have to be similar, for instance the B option,
a+ 55° + 36° = 180°
since you could find the value of a.
The same thing goes for C.
(Extra)
It is not D since x is multiplied with 3, not giving the sum.
It is not E since all the 3 terms are multiplied, not giving the sum.
K = 75
75-25=50
Hope this helps!
Answer:
20.4
Step-by-step explanation:
(15*36)/100+15
One thing is you don't have to put the decimal point before the last two zeros. :D just saying... but if you want to then that's okay.
Anyway doing this scientific notation, you write the number down.
1) 13562600000000.00
Next you write times (x) 10
2) 13,562,600,000,000.00 x 10
Then you write the exponent of the number of places you need to move the decimal. REMEMBER: to make a standard notation to scientific notation the number has to be BETWEEN 1 and 10
3) 1.3562 x 10∧11
It might be 15 for you because you might count the two zeros behind the decimal point in standard form.
I hope this help you out :D
