Answer:
a - b = 12
Step-by-step explanation:
Given
= 12 ← factor the numerator
a² - b² ← is a difference of squares and factors as
a² - b² = (a - b)(a + b)
Thus
= 12
Cancel the common factor (a + b) on numerator/ denominator, thus
a - b = 12
Answer:
c. 2
Step-by-step explanation:
Defining two angles of a triangle means you know the values of all of the angles. When all angles are known and the side opposite one of them is known, then the triangle is completely determined.
In this case, the angle opposite the given side can be either of the two given angles, so two triangles are possible.
__
If the two angles have the same measure, then only one triangle is possible.
