Answer:
x = 32
<1 = 102 degrees
<2 = 78 degrees
Step-by-step explanation:
3x + 6 + 2x + 14 = 180
5x + 20 = 180
5x = 180 - 20
x = 160/5
x = 32
3(32) + 6 = 102 degrees

In the equation, there's an invisible 1 in front of the first d, so let's add that.
1d - 2d - 3d
Since all the terms in the above equations are like terms, we would focus on only subtracting. We would first subtract 2d from 1d.
- 1d - 3d
We then subtract 3d from - 1d. This would give us our answer.

Answers
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
According to above diagram :
RT = RS + ST
that is :
[tex]2x + 75 = 4x + 107 + 12[/tex][tex]2x - 4x = 119 - 75[/tex][tex] - 2x = 44[/tex][tex]x = - 22[/tex]now, RT = 2x + 75
[tex](2 \times - 22) + 75[/tex][tex] - 44 + 75[/tex][tex]31[/tex]hence , RT = 31 units
Answer:
RT = 31
Solve for x:
[tex]x=-22[/tex]
Step-by-step explanation:
==>> The sum of the line is RST
[tex]4x+107+12=RST[/tex]
==>> Since [tex]RST = 2x + 75[/tex], the equation will newly become [tex]4x+107+12=2x+75[/tex]

To find [tex]4x+107[/tex], we need to find the x.

-- Lets check our work
==>> [tex]4(-22) = -88[/tex]
[tex]-88 + 107 = 19 [RS = 19][/tex]
[tex]RS + ST = 19 + 12 =[/tex] 31

[tex]2(-22) = -44[/tex]
[tex]-44 + 75 =[/tex] 31

Find the measure of the indicated angles.show work.complete sentence a. m<QRP = ____
b. m<QRX = ____
Answers
The measure of m<QRX and m<QRP are 129 and 51 degrees respectively.
The sum of the interior angle of a triangle is 180 degrees, hence;
m<QPR + m<QRP + M<PQR = 180
Substitute the given parameters
49 + m<QRP + 80 = 180
m<QRP + 129 = 180
m<QRP = 180 - 129
m<QRP = 51 degrees
The sum of interior angle is equal to the exterior
m<QPR + M<PQR = m<QRX
m<QRX = 49 + 80
m<QRX = 129 degrees
Hence the measure of m<QRX and m<QRP are 129 and 51 degrees respectively.
