Answer : The value of 'x' is, 240°

Step-by-step explanation :

As we know that a circle make an angle of 360°.

As we are given that the two hexagon are joined together to form a resultant figure.

In hexagon, there are 6 sides and 6 angles.

Each interior angle of hexagon = \frac{360}{6}=60^o

In the resultant figure,

\angle x+\angle y+\angle z=360^o

As, \angle y=\angle z=60^o

So,

\angle x+60^o+60^o=360^o

\angle x+120^o=360^o

\angle x=360^o-120^o

\angle x=240^o

Therefore, the value of 'x' is, 240°

Can someone help me plz .. Use these lengths to find cos B, tan B, and sin B.
lara [203]

Answer:

cos B = \frac{7}{25}

tan B = \frac{24}{7}

sin B = \frac{24}{25}

Step-by-step explanation:

In the right triangle, there are three sides and 2 acute angles

  • Hypotenuse ⇒ the opposite side of the right angle
  • Leg1 and Leg 2 ⇒ the sides of the right angle

The trigonometry functions of one of the acute angles Ф are

  • sin Ф = opposite leg/hypotenuse
  • cos Ф = adjacent leg/hypotenuse
  • tan Ф = opposite leg/adjacent leg

In Δ ACB

∵ ∠C is the right angle

∴ AB is the hypotenuse

∵ AC is the opposite side of ∠B ⇒ leg1

∵ CB is the adjacent side of ∠B ⇒ leg2

→ By using the ratios above

∴ cos B = \frac{CB}{AB} , tan B = \frac{AC}{CB} , sin B = \frac{AC}{AB}

∵ CB = 7, AB = 25, AC = 24

∴ cos B = \frac{7}{25}

∴ tan B = \frac{24}{7}

∴ sin B = \frac{24}{25}

Help is very much needed :)
ioda

Answer:

6

Step-by-step explanation:

10/5 ×/3 multiply 10×3 and than divide by 5

or another way start with multiplying 5 and n equaling 5n=

than 10× 3= 30 so you're left with 5n=30 divied 30 by 5 equalling 6

so x=6

Calculate the specific heat of a metal (in calories/gram-degree C) from the following data. A container made of the metal has a
Arisa [49]

Answer:

<h2>The specific heat of the metal is 0.274951 calories/gram-degree C.</h2>

Step-by-step explanation:

Let, the specific heat of the container is x calories/gram-degree C.

The container and water gains (18 - 15) = 3 degrees C.

Hence, the transfer of heat is 3(18.1\times1000\times1) + 3(3.77x\times1000).

The metal, which is dropped in the water, losses (164 - 18)= 144 degrees C.

Hence, the transfer of heat is 144\times 1.45\times1000x.

As per the given conditions,

3(18.1\times1000) + 3(3.77x\times1000) = 144\times1.45\times1000x\\54.3 + 11.31x = 208.8x\\197.49x = 54.3\\x = 0.274951.

f(x)=-3x

Substitute x = 5 in the equation.

f(5)=-3(5)\\f(5)=-15

Therefore, the answer is -15 or last choice when x = 5.
