Answer:
4°
Step-by-step explanation:
All the angles in a triangle add together to equal 180°. We know there are three angles of 20° so let's subtract this.
20° × 3 = 60°
180° - 60° = 120°
Now well divide 120° up among the three angles.
120° ÷ 3 = 40°
Now we know the angles are 40° + 20°, but we need to find the value of x, so divide 40° by 10
40° ÷ 10 = 4°
x = 4°
Answer:
x=3
Step-by-step explanation:
First we should subtract 14 from both sides, getting 64 * 3^x = 1728. Then we can divide by 64 on both sides, leaving us with 3^x=27. x is equal to 3.

Answer:
Upon multiplication with this matrix A, it gives a vector perpendicular to the original, with a magnitude of times of the original.
If a 2x2 matrix A has complex eigenvalues, this is an antisymmetric matrix.
Therefore:
if we multiply (x,y) to this matrix A:
Remember the formula for calculating volume is: Volume = Area by height. V = A X h.
