Answer:
9
in²
Step-by-step explanation:
The area (A) of an equilateral triangle is calculated as
A =
( s is the length of a side )
Here s = 6, thus
A =
=
= 9
in²
First solve the triangle:
75° + 75° + x = 180°
150° + x = 180°
x = 180° - 150°
Therefore x = 30°
Then, use the geometrical property of vertically opposite angles.
Therefore. x° = 30°
Answer:
A. Move the decimal point to the left
Step-by-step explanation:
Given that:
The scientific notation = 10⁻¹⁰
Let recall;
That the standard notation usually took the form of an inverse:
For example;
Let say 10⁻¹ will be
in scientific notation;
SO, 
Now; we are given 10⁻¹⁰ as a scientific notation,
To standard notation, we get:

= 0.01
Thus, it is true to say that the decimal point will be moved to the left side when converting a number from scientific notation to standard notation if the power of 10 is -10.
the answer will be 20 times 3 that is 60
