Answer:
18√2
Step-by-step explanation:
2√18 + 3√2 + √162
= 2√(9 * 2) + 3√2 + √(81 * 2)
= (2 * 3)√2 + 3√2 + 9√2
= 6√2 + 3√2 + 9√2
= (6 + 3 + 9)√2
= 18√2
Answer:
11=x
Step-by-step explanation:
move 21 towards ten and change to positive and then solve it
The type of triangle it is C. equilateral.
Since the triangle has sides measuring 4 cm, 4 cm and 4 cm, all its sides are equal.
Also, two of its angles measure 60°.
<h3 /><h3>Determining the third angle</h3>
We need to determine the third angle.
Let the third angle be x.
So, 60° + 60° + x = 180° (Sum of angles in a triangle)
120° + x = 180°
x = 180° - 120°
x = 60°
Since the third angle is 60°, it implies that all its angles are 60°.
<h3 /><h3>Identifying the triangle</h3>
So, a triangle haing all its angles as 60° and sides equal is an equilateral triangle.
So, the type of triangle it is C. equilateral.
