121^4-49
(11^2+7)(11^2-7) 1. 121. 49
11. × 11. 7 × 7
The answer for that equation will be 0.375.
The numbers -9 and -4 add up to -13 and multiply to get 36
I hope this helped :)
Answer:
Inscribed angle theorem
Step-by-step explanation:
This theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
In this case, the angle is ∠LMN and the arc is arc LN. Arc LN measures 180°, because segment LN is the diameter of the circle. Then, by the theorem:
∠LMN = (1/2)*arc LN = (1/2)*180° = 90°
