The angles in a triangle are in the ratio 3:2:1.
a) Show that the triangle is a right-angled triangle
b) The hypotenuse of the triangle is 25 cm long.
Calculate the length of the shortest side in the triangle

Answers

Answer:

see explanation

Step-by-step explanation:

(a)

sum the parts of the ratio, 3 + 2 + 1 = 6 parts

The sum of the 3 angles in a triangle = 180° , then

180° ÷ 6 = 30° ← value of 1 part of the ratio , then

3 parts = 3 × 30° = 90°

2 parts = 2 × 30° = 60°

1 part = 30°

The angles in the triangle are 90°, 60°, 30°

Thus the triangle is right angled

(b)

The shortest side is opposite the smallest angle, that is opposite 30°

Using the sine ratio in the right triangle and the exact value

sin30° = [tex]\frac{1}{2}[/tex]

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{opposite}{25}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2 × opposite = 25 ( divide both sides by 2 )

opposite = 12.5

That is shortest side is 12.5 cm

Step-by-step explanation:

This is a permutation of 7 letters with double O and double C:

7!/2!2! = 5040/4 = 1260

☆Answer :

P = 1

I = 1

C = 2

O = 2

L = 1

Total (n) = 7(k) = 2(C), 2(O)

8. The temperature on Monday was -5.4 degrees
Celsius. The temperature on Tuesday was 2.6
degrees less than the temperature on Monday.
What was the temperature on Tuesday?

Answers

Answer: -4.1 degrees celsius

Step-by-step explanation:

Start at -1.5 on the number line. Then move 2.6 units to the left to arrive at -4.1

Or you can compute -1.5 - 2.6 = -4.1 to get the same result. When we subtract a number from a negative, you are effectively adding the two values and making the final result negative. So, 1.5+2.6 = 4.1 which turns into -4.1

Find the slope (-10,-3) (7,2) Fascism is generally a military dictatorship based on strong nationalist sentiment, racism and the suppression of opposition by using force. Fascists come to power by exploiting patriotism, racism and fear. Benito Mussolini invented the term in 1925 and used it proudly. Mussolini installed himself as Italy's dictator in 1925. He blamed foreigners for Italy's problems and failed to carry out many of his promises. He also built up Italy's military, and in 1935, invaded Ethiopia. Another famous fascist, Francisco Franco, overthrew the Spanish government in 1936 in the Spanish Civil War. Franco and his fascist rebels won the war largely because of military aid from Germany and Italy. Adolf Hitler, also a fascist, took power in 1933 mainly by blaming outsiders for the humiliating position in which Germany found itself after World War I. War reparations, the hyperinflation of 1923 and then the international economic depression all fed the fascist rhetoric of blaming foreigners and Jews.
