Answer: If two angles of one triangle are congruent to two angles of another triangle, then the third pair of angles is also congruent


Step-by-step explanation:

The <em>third angle theorem</em> says that if two angles in one triangle are congruent to two angles in another triangle, then the third pair of angles must also congruent. This is called the Third Angle Theorem.

Let ΔABC and ΔPQR are two triangles such that

∠A≅∠P and ∠B=∠Q.......(1)

Also ∠R=180°-(∠P+∠Q) [By angles sum property in  ΔPQR ]......(2)

∠C=180°-(∠A+∠B) [By angles sum property in ΔABC]

⇒∠C=180°-(∠P+∠Q)     [from (1)]

⇒∠C=∠R      [from (2)]

Hence proved.

the first winner will receive 1/3 of the money..
1/3 * 2400 = 2400/3 = 800
leaving 2400 - 800 = 1600

the next 10 winners will receive 1/10 of the remaining amount
1/10 * 1600 = 1600/10 = 160 <== each will receive $ 160

A boat heads south at 120 mph while a steamer heads east at 50 mph. If they started from the same dock and at the same time, whe
Snezhnost [94]

Answer:

  1 hour after they leave

Step-by-step explanation:

The distance each travels is proportional to its speed. The given speeds are at right angles to each other in a 5:12 ratio. The Pythagorean theorem tells you the hypotenuse of such a right triangle will have length ...

  √(5²+12²)=√169 = 13

That is the speeds are in the ratio 5:12:13, where 13 represents the relative separation speed. Actual speeds are then 50 mph : 120 mph : 130 mph.

So the distance between the boat and steamer will be increasing at 130 mph. The distance will be 130 miles after 1 hour.
