Answer: 23°, 65° and 92°
Step-by-step explanation:
a + b + c = 180 (The angles of a triangle equals to 180)
a = 4c (the largest angle is 4 times the smallest angle)
b = 4c - 27 (the final angle is 27 less than the largest angle)
c = c
Now that we have gotten the values for the variables in our equation, we plug them in:
4c + 4c - 27 + c = 180
Combine like terms:
4c + 4c + c - 27 = 180
9c - 27 = 180
9c = 180 + 27
9c = 207
Divide both side by 9
c = 23
a= 4c
a = 4 × 23
a = 92
b = 4c - 27
b = 92 - 27
b = 65
b = 65
Check:
a + b + c = 180
92 + 65 + 23 = 180
180 = 180
Answer:
A
Step-by-step explanation:
The denominator in the original question is 5.
Therefore the answer must have 5 in the numerator. The answer can only be A.
6 4/5 = (30 + 4) / 5 = 34/5 This is the original fraction. The upside down of the original fraction is the reciprocal. Upside down of 34/5 is 5/34. You can come to this conclusion by doing this.
The formal definition of a reciprocal is 1/a where a is a fraction.
In this case a = 34/5. The reciprocal is 1/a = 1 // 34/5. You don't change anything by making it 1/1 // 34/5
1/1 // (34/5) Invert and multiply the bottom.
1/1 * 5/34 = 5/34
