What is x equal to ? Link down below.
scZoUnD [109]

Answer:

50

Step-by-step explanation:

Because of supplementary angles that line has to equal to 180

180-75 = 105

so 105 = (2x + 5)

you can subtract 5 from each side and get

100 = (2x)

then divide each side by 2 and you get

x = 50

you can check it by doing (2 x 50 + 5)

2 x 50 = 100 + 5 = 105 + 75 = 180

Please help me!!!!!!!
Helen [10]
First we will find the value of x.

To find the value of x we can add angle Q and angle O and set them equal to 180 and solve for x.

We will be setting them equal to 180 since the opposite angles of an inscribed quadrilateral are supplementary.

angle Q + angle O = 180
6x - 5 + x + 17 = 180
7x +12 = 180
7x = 168
x = 24

Now we can use 24 for x and find the value of angle QRO

angle QRO = 2x + 19
angle QRO = 2(24) + 19
angle QRO = 48 + 19
angle QRO = 67

So the answer choice B is the right answer.

Hope this helps :)<span />

kerry is comparing the number 9.207 and 9.210. what is the least place value she needs to compare to decide which number is grea
andrew11 [14]
The number 9.210 is greater. The least place value is the 0 (Zero) and the 1 (One). This is because the 9 (Nine) and the 2 (Two) in 9.207 and 9.210 is the same numbers. There so, you can't compare those 2 (Two) numbers.
