The value of a is D)73 I think because 180-107 since a straight line is 180 u just subtract the angle from it. hope this helps.
Not 100% sure this is right but
60cm^2
The greatest common factor of the expressions 60x and 84 is 12 because it can divide both 60 and 84 giving us the answer of 5 and 7, respectively. Factoring out 12 from the terms of the given expression will give us the answer of,
60x - 84 = 12(5x - 7)
<h3>a) Never</h3>
{All angles of a rectangle are right}
<h3>b) Always</h3>
{all sides of a rhombus are the same, 4×13=52}
<h3>c) Always</h3>
{oposite angles of a paralleogram are congruent}
<h3>d) Never</h3>
{parallel sides has the same slope}
<h3>e) Always</h3>
{square has all sides of the same length, so it is rhombus}
<h3>f) Sometimes</h3>
{Only if it has angles of 90°}
Answer:
Step-by-step explanation:
- Multiply both the matrices on left side, we find:
- Comparing the corresponding elements of both the matrices on both sides, we find:
