Step 1 :Form two right triangles with the bridge's height as the opposite side and the distance from the bridge as the adjacent side.
Step 2 :Denote the height of the bridge as h, the distance from the first point to the center of the creek under the bridge as x, and the distance from the second point to the center of the creek under the bridge as y.
Step 3 :From the first angle, we have: \(\tan(26^\circ) = \frac{h}{x}\)
Step 4 :From the second angle, we have: \(\tan(47^\circ) = \frac{h}{y}\)
Step 5 :We also know that x + y = 150m (the distance between the two points).
Step 6 :Solve these equations to find the height of the bridge.
Step 7 :angle1 = 26, angle2 = 47, distance = 150
Step 8 :x = 46.89, y = 103.11
Step 9 :height = 22.87
Step 10 :\(\boxed{\text{The height of the bridge is approximately 22.87 meters}}\)
