Answer:
. In other words, these two angles are both right angles, and this parallelogram would be a rectangle.
Step-by-step explanation:
Two angles that congruent have the same size.
At the same time, those two adjacent angles of this parallelogram would be a pair of consecutive interior angles. Because the two sides of a parallelogram are parallel to one another, the sum of these two consecutive interior angles would be - they are supplementary to one another.
Let the two angles be and .
because the two angles are congruent.
because these two angles are adjacent angles of a parallelogram.
Hence, .
Answer:
a = 9
Step-by-step explanation:
For solve the problem we can use the Pythagorean theorem in this way
a^2 + (3√3)^2 = (6√3)^2
If we solve the equation we have
a^2 + 27 = 108
a^2 = 81
a = +/-9
we take only the the positive value because a length can’t be negative
a = 9
In 10 mins 46 chains
46x 6.59 = $303.14
It’s 3/5 since it should be adjacent/hypotenuse and 4 is the opposite
