The interior angles in a 4 sided polygon add up to 360°. You are already given two measurements of 90°, so you know that the lastvtwo angles sum to 360-90-90= 180°.
Put this information into an equation and solve for x:
(7x+27)°+(9x-7)°=180°
7x+27°+9x-7°=180°
16x+20°=180°
16x=160°
x=10°
Angle B is (7x+27)°, so just substitute x:
B = 7(10)+27
B = 70+27
B = 97°

The place to start is with this fact: the sum (total) of all the angles of a quadrilateral is 360 degrees.  You know the two right angles (90 degrees each), so

90 + 90 + (7x + 27) + (9x - 7) = 360

Simplify and solve.

180 + 16x + 20 = 360
16x + 20 = 180
16x = 160
x = 10

Now plug this in for x in the two "algebra" angle measures.

Express 2x^2+8x+3 in the form 2(x+p)^2+q
e-lub [12.9K]

Answer:

2(x + 2)² - 5

Step-by-step explanation:

Given

2x² + 8x + 3

To obtain the required form use the method of completing the square.

The coefficient of the x² term must be 1, thus factor 2 out of 2x² + 8x

= 2(x² + 4x) + 3

add/subtract ( half the coefficient of the x- term)² to x² + 4x

= 2(x² + 2(2)x + 4 - 4) + 3

= 2(x + 2)² - 8 + 3

= 2(x + 2)² - 5

with p = 2 and q = - 5

Given that ABCD is a rhombus, what is the value of x?<br>(3x - 26)​
ExtremeBDS [4]
<h2>The required "option B) 20.75\°" is correct.</h2>

Step-by-step explanation:

You can refer figure:

brainly.com/question/4386376

To find, the value of x = ?

We know that,

Consecutive angles are supplementary

The diagonals bisect the angles.

2x\°+2(3x+7)\°=180\°

Divided by 2 both sides, we get

⇒ x\°+(3x+7)\°=90\°

⇒ x\°+3x+7\°=90\°

⇒ 4x=90\°-7\°

⇒ 4x = 83\°

⇒ x=\dfrac{83\°}{4}

⇒ x=20.75\°

∴ The value of x =20.75\°

Thus, the required "option B) 20.75\°" is correct.
