Mathematics
1 answer:
sammy [17]3 years ago

Answer:

a = 12cm

Third option

Step-by-step explanation:

Use the pythagorean theorem because this is a right triangle and you are looking for a missing side.

The formula is:

a² + b² = c², where "a" and "b" are sides, but "c" is the hypotenuse (longest side).

We know the hypotenuse and one other side.

Substitute side "b" and "c".

a² + 5² = 13²

a² + 25 = 169   Isolate "a"

a² = 169 - 25    Subtract 25 from both sides

a² = 144         Find the square root of both sides

a = √144

a = 12

The mssing side, "a", is 12 cm long.

2. If ¡2x+3 = i, where i = V-1, then which of the
Alexus [3.1K]

I assume you mean the equation

i^{2x+3} = i

Since i = √(-1), we have i⁴ = 1 and so i⁵ = i. Then 2x + 3 must be some multiple of 5.

Now just check for which of the given choices that this holds:

x = 16   ⇒   2x + 3 = 35   (yes)

x = 11   ⇒   2x + 3 = 25   (yes)

x = 10   ⇒   2x + 3 = 23   (no)

x = 14   ⇒   2x + 3 = 31   (no)

Use the diagram to find the measure of angle KHL.
bija089 [108]

Answer:

m∠KHL = 43°

Step-by-step explanation:

From the picture attached,

m∠KHL ≅ m∠GHL [Given in the picture]

Now substituting the values of the angles,

(3x + 1) = (5x - 27)

1 + 27 = 5x - 3x

28 = 2x

14 = x

m∠KHL = (3x + 1)° = (3 × 14) + 1

                             = 42 + 1

                             = 43°

Therefore, measure of ∠KHL = 43°

To rent a certain meeting room a college charges a reservation fee of $33 and an additional fee of $9.80 per hour the club wants
sammy [17]

Answer:

They must rent for less than 7 hours

Step-by-step explanation:

The charge for the room is the fee plus the hourly rate times the hour

f = 33+9.80t

This must be less than 101.60

101.60> 33+9.80t

Subtract 33 from each side

101.60-33> 33-33+9.80t

68.6> 9.80t

Divide each side by 9.8

68.8/9.8 > t

7>t

They must rent for less than 7 hours
