Ef=19, as given in the question.
The answer is 90 + 45 because BOC is a right angled triangle where angle BOC is 90 and angle BOK is 45 because 90 ÷2. A OK Is a right angled triangle so angle AOB is 90 as well so to find angle AOK we plus 90 and 45 which is 135 degrees.
Answer:
102°
Step-by-step explanation:
that's the answer because 40+ 38 = 78. then 180- 78 = 102. Remember that in tringles, all three angles should add up to 180°
1) -30 meters because descend means decrease
2) 20 meters because above means positive
3) 0 because it does not change
Hope this helps!
