Determine the area of the triangle when tana=1 the image is in the picture above

The area will be:

or .

Step-by-step explanation:

Using the definition of tangent, we have:

We know that tan(α) = 1, then we can find AB

u means any unit.

Now, we need to find the distance BC. If the angle ∠D is 60°, then ∠C must be 30°. Using the tangent definition in the triangle BCD we have:

So, the base of the triangle will be:

The area of a triangle is given by the following equation:

Therefore, the area will be .

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:
