Answer:
(2a - )(2a +
)
Step-by-step explanation:
4a² - ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
4a² -
= (2a)² - ( )²
= (2a - )(2a +
)

The diagram of the triangle is shown below
One interior angle is 56°
One exterior angle is 103° ⇒ we can work out one interior angle 180°-103° = 77°
The other interior angle is 180° - (56°+77°) = 44°
