The angular measure L is : 47°
<h3>What are angles?</h3>
Angles are formed when two lines meet.
Analysis:
Firstly, we calculate for m using cosine rule.
=
+
-2(510)(820) cos 20
= 260100 + 672400 -83600(0.9396)
= 146618.56
m =
= 382.9cm
using sine rule to find ∠L
382.9/sin20 = 820/sinL
sinL = 820sin20/382.9
sinL = 820(0.342)/382.9
sinL = 0.732
L = sin inverse of 0.732 = 47°
In conclusion, ∠L is 47°

Answer: The graph shown
Step-by-step explanation:
Another graph of the function is attached in this answer.
Answer:
Option C is correct.
Step-by-step explanation:
Given: A rhombus. m∠1 = 40°
To find: m∠2
We know that Rhombus is a parallelogram with all equal sides.
⇒ Opposite sides of the Rhombus are parallel.
Then Diagonal act as a traversal for parallel sides.
So, m∠2 = m∠1 ( Alternate Interior Angles are equal )
m∠2 = 40°
Therefore, Option C is correct.
