Find the missing angles using either the triangle sum theorem (a2+b2=c2) or inverse trigonometric ratios
2 answers:
using trigonometry:-
cos of angle ? = 7/16
so ? = arccos 7/16 = 64.06 degrees
The other angle is 90 - 64.06 = 25.94 degrees
The other angle is 29.53 degrees

Answer:
j = 4.29
Step-by-step explanation:
9.8j - 6 = 36
+ 6 +6
9.8j = 42
