Hello,

x+2+x+74=180

2x+76=180

2x=180-76

2x=104

2x/2=104/2

x=52

Good lessons!

Answer:

x = 52 i hope this helps! :)

Step-by-step explanation:

so first you gotta realize that every triangle has an interior angle measurement sum of 180 degrees

so we are given 3 angles 74 degrees x + 2 and x

we now are going to put this into an equation 74 + x + 2 + x = 180

now lets combine like terms to get 76 + 2x = 180

then we are going to subtract the 76 from both sides 2x = 104

now lets divide both sides by 2 x = 52

so x = 52

we can plug in the value of x into both of the other equations to find the angle measurement

52 degrees

52 + 2 = 54 degrees

and then we have 74 degrees

add the 52, 54, and the 74 to make sure it is equal to 180 degrees

106 + 74 = 180

so yes, x does indeed equal 52 degrees

Find the area of the parallelogram, trapezoid, rhombus, or kite. Round to the nearest tenth, if necessary.

Sergeeva-Olga [200]

Answer:

69.3 yd²

Step-by-step explanation:

Area equation of the parallelogram

A = bh, where b- base, h - height

Looking at the picture, we can see the right triangle is isosceles as one of interior angles is 45°. It has hypotenuse of 7 and legs of h.

As per property of 45° right triangle the hypotenuse is √2 times the leg.

It gives us

h√2 = 7 ⇒ h = 7/√2 = 4.95 (rounded)

Now find the area

A = 14*4.95 = 69.3 yd²

Question is attached

Neporo4naja [7]

Answer: C

Step-by-step explanation: The standard equation is Ax + By = C

To solve for this, first solve for the slope: y2 - y1 / x2 - x1

0 - 5 / 4 - 0 = -5 / 4

Plug the slope and ordered pair of (0, 5) into the equation y - y1 = m(x - x1)

y - 5 = -5/4(x - 0)

Add 5 to both sides: y = -5/4x + 5

Subtract y and 5: -5 = -5/4x - y

Multiply the entire equation by 4: -20 = -5x - 4y

(or multiply entire equation by -4 to get 20 = 5x + 4y)

Godel is asked to perform the addition problem below. Godel believes that because there are more negative numbers, the answer wi

dem82 [27]

Answer:

$-7+12-3+9+(-5)=6$

Godbel is wrong in the reasoning as the answer does not depend on the number of negative numbers in the expression. Instead it depends on the value of the sum of positive terms and the value of the sum of negative terms. If the values of sum of positive terms is greater than the value of the sum of negative terms then the answer will be a positive and vice versa.

Step-by-step explanation:

Given expression:

$-7+12-3+9+(-5)$

To evaluate the expression.

Solution:

We have: $-7+12-3+9+(-5)$

Removing parenthesis first as a positive and negative multiply to give a negative.

⇒ $-7+12-3+9-5$

Then we can group the positives and negatives together.

⇒ $12+9-7-3-5$

⇒ $21-7-3-5$

Since the negatives combine by getting added up with the sum being negative, so we have:

⇒ $21-15$

As, we can see the positive value (21) is greater than the negative value (15) and hence the answer would be a positive.

⇒ 6

Which equation represents the slope-intercept form of the line below?

Alekssandra [29.7K]

Y = -3x + 5

When creating a line in slope intercept form, the -3 always goes right next to the x after the equals sign. Also, the y intercepts y value (the second part of the parenthesis) just gets added on at the end of the equation.
