Check the picture below tell me if you understand what I did.
Right angle=90°.
(X-20) + X = 90.
Then solve for X.
X=55
Answer:
55°
Step-by-step explanation:
Using cosine law
67² = 74² + 14² - 2(74)(14)cos(L)
cos(L) = 169/396
L =55.18378419
If n = –2, then m is equal to 13;
If n = 0, then m is equal to 7;
If n = 1, then m is equal to 4
0.1846 as a fraction=1846\10000
