Find the area of the circles: 1. f. Answer: 379.94 square inches 2. ... Given the radius or diameter, find the circumference AND area of each circle to the nearest tenth. 5. r=9 m. C=56.52 m. A=254.34 square meters ... Round your answer to the nearest tenth. 50.2 square feet 9. A company is manufacturing aluminum lids.
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.

sorry I can't answer that because I need points very3× sorry
It would be a x/n = n √a^x
Hope this helps
Trini took 74 photos
<em><u>Solution:</u></em>
Given that Trini took some photos
The number of photos she took is a two-digit number
Let the number in unit place be x and the number in tens place be y
Then the two digit number is yx
Given that sum of digits is 11
Therefore,
x + y = 11 ---- eqn 1
The tens digit is 3 more than the ones digit
Therefore, we frame a equation as,
y = 3 + x ---- eqn 2
<em><u>Solve eqn 1 and eqn 2 to get value of "x" and "y"</u></em>
Substitute eqn 2 in eqn 1
x + 3 + x = 11
2x + 3 = 11
2x = 11 - 3
2x = 8
x = 4
Substitute x = 4 in eqn 2
y = 3 + 4 = 7
Thus the two digit number is 74. Thus he took 74 photos
