14
Step-by-step explanation:
Given:
Number = -9.1
To find:
The magnitude (size) of given number.
Solution:
We know that, magnitude of a number is the absolute value of that number.
So, magnitude of -9.1 is

Because, absolute value of a number is always positive.
Magnitude of -9.1 is 9.1 because
.
Therefore, the correct option is A.
Answer:
B.
Step-by-step explanation:
1/4 Is the same as saying 25%.
1 x 64=64
2 x 32=64
4 x 16 =64
8x8=64
Let the third angle be x.
Sum of the interior angles of a triangle = 180°
42 + 84 + x = 180
126 + x = 180
x = 180 - 126
x = 54°
Hence, the third angle is 54°.
