Work out angle x 55°

Answers

Answer 1

Answer:

70°

Step-by-step explanation:

We know that the triangle is an iscoceles based on the 2 small lines drawn horizontally on 2 sides of the triangle.

We know that the base angles in an iscoceles triangle are the same, so the angle that has not been drawn is 55°.

55° + 55° = 110°

180° - 110° = 70° (180 comes from the entire triangle adding up to 180°)

Step-by-step explanation:

Area of the surface of the cuboidal box to be painted = surface area of the cuboidal box - area of the base

✔️Surface area of the cuboidal box = 2(L*W + W*H + L*H)

L = 6 cm

W = 4 cm

H = 2.5 cm

Surface area of the cuboidal box = 2(6*4 + 4*2.5 + 6*2.5) = 2(24 + 10 + 15) = 2(49)

Surface area of cuboidal box = 98 cm²

✔️Area of base = L*W

= 6*4 = 24 cm²

Area of the cuboidal box to be painted = 98 - 24 = 74 cm²

✔️Cost of painting 74 cm² at Rs. 4.50 per cm² = 74 × 4.50 = Rs. 333

(4,−4), (k,−1); m=3/4 i need to know what k is

Answers

Answer:

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

3/4=(-1-(-4))/(k-4)

3/4=(-1+4)/(k-4)

3/4=3/(k-4)

cross product

4*3=3(k-4)

If a series RC circuit is operating at 100 VAC and has an impedance of 52.5 ohms, what is the circuit current

Answers

Answer:

1.9 Amps

Step-by-step explanation:

In an RC circuit, the relationship between the current I in amps, the impedance Z in ohms and the voltage V in volts may be stated as

V = IZ

As such, given that z = 52.5 ohms and V = 100 Volts, the current in the circuit I may be computed as

100 = I * 52.5

Divide both sides by 52.5

I = 100/52.5

= 1.9 Amps

A cylindrical container contains some sand. If the diameter of the container is 10 inches and its height is 3 inches, about how much sand fits inside the container?

Answers

Answer:

251.33in²

Step-by-step explanation:

A cylindrical container contains some sand. If the diameter of the container is 10 inches and its height is 3 inches, about how much sand fits inside the container?

We solve the above question using the formula for Total surface area of a cylinder.

TSA = 2πr (h + r) Square units.

Where

h = Height of the cylinder

r = Radius of the cylinder

Diameter of the container is 10 inches

Hence, radius = Diameter/2 = 10/2 = 5 inches

Height is 3 inches.

Hence, Total surface area =

2 × π × 5 (5 + 3)

= 10π × (8)

= 251.32741229 in²

Approximately = 251.33 in²

Therefore, the amount of sand that can fit into the cylinder = 251.33 in²
