Height of the flagpole before it broke was 32 m
Step-by-step explanation:
- Step 1: This forms a right angled triangle with height 7 m and base 24 m. Find the hypotenuse using the Pythagoras Theorem.
Hypotenuse² = Base² + Height²
= 24² + 7² = 576 + 49 = 625
∴ Hypotenuse = √625 = 25 m
- Step 2: Find the height of the flagpole before it broke.
Since the stuck 7 m and the remaining part which is the hypotenuse together make the flagpole.
⇒ Height = 7 m + 25 m = 32 m

Answer: angle B = 47 degrees</h3>
========================================
Work Shown:
Use law of cosines to find angle B
b^2 = a^2 + c^2 - 2*a*c*cos(B)
9^2 = 6^2 + 12^2 - 2*6*12*cos(B)
81 = 36 + 144 - 144*cos(B)
81 = 180 - 144*cos(B)
81 - 180 = -144*cos(B)
-99 = -144*cos(B)
-144*cos(B) = -99
cos(B) = (-99)/(-144)
cos(B) = 0.6875
B = arccos(0.6875)
B = 46.5674634422102
B = 47 when rounding to the nearest whole number
Make sure your calculator is in degree mode.
arccos is the same as inverse cosine often labeled on calculators.
