Plz me with geometry !
the picture below shows a portion of a river dam: a right angle triangle is shown with acute angle on base equal to 50 degrees and the length of base equal to 115 meters. which of the following can be used to calculate the height of the river dam?

The information given in relation to the 50 degree angle is the adjacent side (115) and we need to find the opposite side (height).
The trig ratio to use is the Tangent ratio: Tan = opp/adj

Tan 50 = opp/115

Use algebra to solve.
Multiply both sides by 115

115Tan50 = x
x = 137 m

Tan 50= x/115
x=tan 50(115)
x=137

Hi! mark me brainliest if i : )y = 0.213x – 352.0    represents this linear model shown in the data table.plug in the values of x into the equation for a double check.let's try 1980.y = 0.213(1980) – 352.0y = 69.74which is closest to the 70.1 whereas other options do not satisfy the condition.
