Answer:
B. 70
Step-by-step explanation:
We have the sum given by
Now, we open the summation by substituting the values of 'i',
i.e. = (1+11) + (2+11) + (3+11) +(4+11) +(5+11)
i.e. = 12 + 13 + 14 + 15 + 16
i.e. = 70.
Hence, the sum of is 70.
So, option B is correct.
Answer:
1. False
2. False
3. True
Step-by-step explanation:
The Pythagorean theorem can tell you the length of "b".
c² = a² + b²
b² = 19² -3² = 360
b = 6√10 ≈ 18.8
Sin = Opposite/Hypotenuse
sin(A) = a/c = 3/19
A = arcsin(3/19) ≈ 9.1°
B = 90° - A = 80.9°
The remaining sides and angles are ...
b = 18.8
A = 9.1°
B = 80.9°
Answer: The shape is a rectangle. We know this because it has 4 corners and 4 sides. And it is a quadrilateral.
