You can use trigonometry specially the cos rule in this case. I can’t send the other pictures. But using the cos rule you can check whether the angle is 90
Answer:
x = 11.4 m
y = 21 m
man's shadow = 9.6 m
Step-by-step explanation:
measure of third angle must be 50 degrees (180 - (40 + 90))
you can take tan50° = 15/y and 'y' will equal approx. 21
to find 'x' you can take tan21° = (21-x) /25 and 21 - x = 25 · tan21°
21 - x = 9.6
-x = -11.4
x = 11.4
man's shadow is the difference of 21 and 11.4, which is 9.6
Answer:
THE ANSWER IS OPTION B
Because it has angles and all of them are not the same measure
