Step-by-step explanation:
Sum of all angles in a triangle = 180
3rd angle = 180 - 150 = 30
Answer: A
Answer:
<h3>The answer is option A</h3>
Step-by-step explanation:
Angles in a triangle add up to 180°
Since it's a right angled triangle one of it's angles is 90°
So for angle F we have
F + 25 + 90 = 180
F = 180 - 115
<h3>F = 65°</h3>
To find GH we use tan
tan 25 = FG / GH
FG = 7m
tan 25 = 7 / GH
GH = 7 / tan 25
<h3>GH = 15.0 m</h3>
To find FH we use sine
sin 25 = FG / FH
sin 25 = 7 / FH
FH = 7/sin 25
<h3>FH = 16.6 m</h3>
Hope this helps you
Answer:
To calculate the gradient of a straight line we choose two points on the line itself. The difference in height (y co-ordinates) ÷ The difference in width (x co-ordinates).
so it is 0.2
