Answer:

$\huge{ \boxed{ \bold{ \sf{ \pink{80°}}}}}$

Step-by-step explanation:

✰ $\underline{ \sf{First, \: Let's \: learn \: about \: internal \: angles \: of \: a \: triangle}}$

The angles which are formed inside by the joining of arms of a triangle is called interior angles of a triangle. According to the figure provided , In ∆ ABC , ∠ABC , ∠ ACB , ∠ BAC are interior angles because they lie inside the ∆ ABC and sum of such interior angles is always 180°.

❀ $\sf{Now, \: Let's \: solve} :$

☄ $\underline{ \underline{ \sf{Provided : }}}$

∠B = 3x°
∠ C = 4x°
∠ A = 2x°

☄ $\underline{ \sf{To \: Find :}}$

Measure of C

✏ $\text{Set \: up \: an \: equation \: and \: solve \: for \: x.}$

$\text{{∠a \: + \: ∠ \: b \: + \: ∠ \: c \: = \: 180 \degree}}$

→ $\sf{2x + 3x + 4x = 180 \degree}$

→ $\sf{9x = 180 \degree}$

→ $\sf{ \frac{9x}{9} = \frac{180 \degree }{9} }$

→ $\sf{x = 20 \degree}$

The value of x is 20°. As we are asked to find the measure of ∠C , substituting the value of x in 4x :

$\text{∠c = 4x}$

→ $\sf{∠ \: c \: = 4 \times 20 \degree}$

→ $\boxed{ \bold{ \pink{ \sf{∠c \: = 80 \degree}}}}$

Hence , The measure of ∠ C is 80 °

g Suppose that a die is rolled twice. What are the possible values that thefollowing random variables can take on:(a) the maximu

KengaRu [80]

Answer:

(a) A = {1, 2, 3, 4, 5, 6}

(b) B = {1, 2, 3, 4, 5, 6}

(d) D = {-5, -4, -3, -2, -1, -0, 1, 2, 3, 4, 5}

Step-by-step explanation:

Assume each roll can result in the numbers 1, 2, 3, 4, 5, or 6.

(a) If both rolls result in a 1, the maximum value is 1. If either roll results in a 6, the maximum value is 6; all integers between 1 and 6 are also possible. Therefore, the possible values are:

A = {1, 2, 3, 4, 5, 6}

(b) If either roll results in a 1, the minimum value is 1. If both rolls result in a 6, the minimum value is 6; all integers between 1 and 6 are also possible. Therefore, the possible values are:

B = {1, 2, 3, 4, 5, 6}

(c) If both rolls result in a 1, the sum is 2. If both rolls results in a 6, the sum is 12; all integers between 2 and 12 are also possible. Therefore, the possible values are:

C = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

(d) If the first roll results in a 1 and the second results in a 6, the result is -5. On the other hand, if the first roll results in a 6 and the second results in a 1, the result is 5; all integers between -5 and 5 are also possible. Therefore, the possible values are:

D = {-5, -4, -3, -2, -1, -0, 1, 2, 3, 4, 5}

Answer:

Step-by-step explanation:

This explanation mostly depends on what you're learning right now. The first way would be to convert this matrix to a system of equations like this.

g + t + k = 90

g + 2t - k = 55

-g - t + 3k = 30

Then you solve using normal methods of substitution or elimination. It seems to me that elimination is the quickest method.

g + t + k = 90

-g - t + 3k = 30

____________

0 + 0 + 4k = 120

4k = 120

k = 30

No you can plug this into the first two equations

g + t + (30) = 90

g + t = 60

and

g + 2t - (30) = 55

g + 2t = 85

now use elimination again by multiplying the first equation by -1

g + 2t = 85

-g - t = -60

_________

0 + t = 25

t = 25

Now plug those both back into one of the equations. I'll just do the first one.

g + (25) + (30) = 90

g = 35

Therefore, we know that Ted spent the least amount of time on the computer.

The second method is using matrix reduction and getting the matrix in the row echelon form, therefore solving using the gauss jordan method. If you would like me to go through this instead, please leave a comment.

Julie decided to grow a plant from a seed. She measured the height of her plant each day for 30 days.

k0ka [10]

The given formula is f(t) = 0.4t

They want to solve for f(10), replace t in the formula with 10"

f(10) = 0.4(10)

Multiply:

f(10) = 4 centimeters.
