Remember that there are always 360 degrees in a full circle. Since $m\angle1 = 90^{\circ}$ (it is a right angle), we can find:

$m\angle2 + m\angle3 = 270^{\circ}$

Substituting in the values provided in the problem into our equation gives us:

$(x - 7) + 2x = 270$

$3x - 7 = 270$

$x = \dfrac{277}{3}$

Given this, we can find the $m\angle3$ :

$m\angle3 = 2\Bigg( \dfrac{277}{3} \Bigg) ^{\circ}$

$m\angle3 = \boxed{\dfrac{554}{3}^{\circ} \approx 184.67^{\circ}}$

Express these system specifications using the propositions p “The user enters

Alex73 [517]

Answer:

a) r ⋀~p

b)(r⋀p)⟶q

c) ~r ⟶ ~q

d) (~p ⋀r) ⟶q

Step-by-step explanation:

To solve this question we will make use of logic symbols in truth table.

We are told that;

p means "The user enters

a valid password,”

q means “Access is granted,”

r means “The user has paid the

subscription fee”

A) The user has paid the subscription fee, but does not enter a valid

password.”

Fist part of the statement is correct and so it will be "r". Second part of the statement is a negation and will be denoted by ~p. Since both statements are joined together in conjunction, we will use the conjuction symbol in between them which is "⋀" Thus, we have; r ⋀~p

B) Still using logic symbols, we have;

(r⋀p)⟶q

⟶ means q is true when r and p are true.

C) correct symbol is ~r ⟶ ~q

Since both statements are negation of the question. And also, if ~r is true then ~q is also true.

D) Similar to answer A to C above, applying similar conditions, we have (~p ⋀r) ⟶q

1/3y+11=1/2y-3 What is y???

JulijaS [17]

Answer:

y = 84

Step-by-step explanation:

1) add 3 to both sides of your equation to cancel out the -3

end up with: (1/3)y + 14 = (1/2)y

2) multiply both sides of your equation by 2 to cancel out the (1/2)

end up with: (2/3)y + 28 = y

3) subtract (2/3)y from both sides of the equation to cancel out the positive (2/3)y

end up with: 28 = (1/3)y

4) multiply both sides of the equation by 3 to cancel out the (1/3)

end up with: 84 = y

Plot the points on a graph.A(0,0);B(0,2);C(2,2);D(2,0). Join AB, BC,CD and AD. What is the figure formed? Find the area of the f

$\large \green{ \underline{ \blue{ \boxed{\bf{ \red{Given -}}}}}}$

Four points which lie at (0,0) ; (0,2) ; (2,2) ; (2,0)

$\large \green{ \underline{ \blue{ \boxed{\bf{ \red{To \: Find-}}}}}}$

What is the figure formed?What is the area of the figure?

$\large \green{ \underline{ \blue{ \boxed{\bf{ \red{Solution-}}}}}}$

The given points lie on graph as per the order given in the attachment.

Which shape?

As the points lie 2 units apart from their adjacent sides. It can be a square or rhombus.

The opposite pairs of sides are also parallel to each other. The adjacent sides of the figure formed are also perpendicular to each other.

Hence! the figure formed is a square.

What is the area?

$\large{\sf{ \longmapsto Area_{(square)} = s \times s}}$

$\large{\sf{ \longmapsto Area_{(square)} = {s}^{2} }}$

$\large{\sf{ \longmapsto Area_{(square)} = {(2)}^{2} }}$

$\large{\sf{ \longmapsto Area_{(square)} = 4 \: sq. \: units}}$

What is the product? (-2x- 9y2 )(-4x-3)

lara [203]

Answer:

$36xy^2 + 8x^2 + 27y^2 + 6x$

Step-by-step explanation:

Use the FOIL method of multiplying binomials.

First term in each binomial: $-2x * -4x = 8x^2$

Outside terms: $-2x * -3 = 6x$

Inside terms: $-9y^2 * -4x = 36xy^2$

Last term in each binomial: $-9y^2 * -3 = 27y^2$

Now, rearrange the terms correctly. $36xy^2 + 8x^2 + 27y^2 + 6x$

This is our final answer, since it can not be simplified any more.
