The sides of a triangle are in the ratio 3 : 4 : 5. What is the length of each side if the perimeter of the triangle is 90 cm

[ad_2]

[ad_1]

A. The area of a square is given as:

A = s^2

Where s is a measure of a side of a square. s = (2 x – 5) therefore,

A = (2 x – 5)^2

Expanding,

A = 4 x^2 – 20 x + 25

B. The degree of a polynomial is the highest exponent of the variable x, in this case 2. Therefore the expression obtained in part A is of 2nd degree.

Furthermore, polynomials are classified according to the number of terms in the expression. There are 3 terms in the expression therefore it is classified as a trinomial.

C. The closure property demonstrates that during multiplication or division, the coefficients and power of the variables are affected while during multiplication or division, only the coefficients are affected while the power remain the same.

a=5.3, b=7, c=4.

The smallest angle is ∠C because it is opposite the shortest length of 4.

From the Law of Cosines,

c² = a² + b² – 2ab cosC

or

cos C = (a² + b² – c²)/(2ab)

= (5.3² + 7² – 4²)/(2*5.3*7)

= 0.823

∠C = arcos(0.823) = 34.58°

This answer agrees reasonably with 34.38°

hypotenuse = √(5²+8²) = √89 ≈ 9.4 in.

If 5 in is the leg and 8 in is the hypotenuse:

other leg = √(8²-5²) = √39 ≈ 6.2 in.

The difference between the two possible lengths of the third side =

9.4 – 6.2 = 3.2 in.

[ad_2]

[ad_1]

Given:

a=25 ft, ∠B=65°, ∠C=38°.

Because angles in a triangle sum to 180°, therefore

∠A = 180 – 65 – 38 = 77°.

Apply the Law of Sines to find b and c.

b/sin(B) = a/sin(A)

b/sn(65°) = 25/sin(77°)

b = [sin(65)/sin(77)]*25 = 23.254 ft

c/sin(C) = a/sin(A)

c/sin(38) = 25/sin(77)

c = [sin(38)/sin(77)]*25 = 15.796 ft

The length of stone work required is

a + b + c

= 25 + 23.254 + 15.796

= 64.05 ft

Answer: 64 ft (nearest integer).

The other triangle has a vertical side of 9 and a horizontal side of 21. Could the hypotenuses of these two triangles lie along the same line? (4 points) Yes, because they are both right triangles Yes, because they are similar triangles No, because they are not similar triangles No, because one is larger than the other

When the nurse assesses the client’s right side, there will probably be decreased breath sound. Pneumothorax refers to the presence of air or gas in the pleural cavity resulting in removal of the lungs from the chest wall. On examination breath sounds are usually absent on the affected part of the chest.
