Complete the proof of the Pythagorean theorem. Given: is a right triangle, with
a right angle at .

Prove:

triangle
A right triangle B C A. Angle C is marked as a right triangle. Side B C is labeled as a. Side C A is labeled as b. A line segment drawn from vertex C intersects the line segment B A at a point labeled as D. Segment B D is labeled as x. Segment D A is labeled as y. Angle C D A is marked as a right angle. A line segment that runs parallel to segment BA is labeled as c.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
