D<br> الا<br> 3x+3<br> 4x+2<br> Determine the value of mZDCB.
Anvisha [2.4K]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

The given Angles (4x + 2) and (3x + 3) are forming linear pair, so

  • 4x + 2 + 3x + 3 = 180

  • 7x + 5 = 180

  • 7x = 180 - 5

  • 7x = 175

  • x =  \dfrac{175}{7}

  • x = 25

now, let's find Angle DCB :

  • 3x + 3

  • (3 \times 25) + 3

  • 75 + 3

  • 78 \degree

Can someone help me with this problem
Yuri [45]

Answer:

For this problem, simply substitute x in y=2(3)^x with the given x-values. The resulting coordinates should be (-3,2/27), (-2,2/9), (-1,2/3), (0,2), (1,6), (2,18), and (3,54). Now, you can plot the points, in order to get the exponential graph.

In quadrilateral QRST, Angle R S T measures (5x+15)°. Angle TQR measures (4x+3)°. Circle P is inscribed with quadrilateral Q R S
Assoli18 [71]

Answer:

105degrees

Step-by-step explanation:

Using the theorems that states that the sum of the opposite side of the quadrilateral is 180degrees, hence;

<RST + <TQR = 180

5x+15 + 4x+ 3 = 180

9x + 18 = 180

9x = 180 - 18

9x = 162

x = 162/9

x = 18

Since <RST = 5x+15

<RST = 5(18) + 15

<RST = 90 + 15

<RST = 105degrees

Hence the measure of <RST is 105degrees
