the Pythagorean Theoremproof of let ΔABC be a right triangle. and sinA=a/c, and cosA= b/ca opposite side of the angle Ab the adjacent side of the angle Aand c is the hypotenuswe know that sin²A +cos²A= (a/c)²+ (b/c) ², but sin²A +cos²A=1so, a²/c²+ b²/c ²=1 which implies a²+ b²=c² the answer is Transitive Property of Equality proof the right triangles BDC and CDA are siWe start with the original right triangle, now denoted ABC, and need only one additional construct - the altitude AD. The triangles ABC, DBA, and DAC are similar which leads to two ratios:AB/BC = BD/AB and AC/BC = DC/AC.Written another way these becomeAB·AB = BD·BC and AC·AC = DC·BCSumming up we getAB·AB + AC·AC= BD·BC + DC·BC = (BD+DC)·BC = BC·BC.so not in the proof is Transitive Property of Equality
The surface area of cylinder is 8.625
, if the cylinder has 5 centimeters high and 1.5 cm of diameter.
Step-by-step explanation:
The given is,
Cylinder has a 5 centimeters height
Diameter of the cylinder is 1.5 centimeters
Step:1
Formula for the surface area of cylinder is,
......................................(1)
Where,
h - Height of cylinder
r - Radius of cylinder
From the values of h and r,

= 
r = 0.75 cm
From the formula,
= ( 2 ×
× 0.75 × 5 ) + ( 2 ×
×
)
= ( 7.5
) + ( 1.125
)
A = 8.625

Result:
The surface area of cylinder is 8.625
, if the cylinder has 5 centimeters high and 1.5 cm of diameter.
The horizontal distance covered by pilot is 17,972.2 feet.
Step-by-step explanation:
Given,
Distance covered descending = 1000 feet
Diagonal distance = 18,000 feet
The horizontal distance will form a right triangle, therefore, we can find the horizontal distance by using pythagoras theorem.
Here,
a = 1000
b = horizontal distance
c = 18000

Taking square root on both sides

The horizontal distance covered by pilot is 17,972.2 feet.
