Answer:Angle MNO=105°

x=21°

Step-by-step explanation:Angle MNO+Angle TUV=180°

75+5x=180°

5x=105°

x=21°

RS=2x-8, ST = 11, RT = x+10

ziro4ka [17]

Answer:

$Equation~=~\Large\boxed{2x+3=x+10}$

$x~=~\Large\boxed{7}$

$RS~=~\Large\boxed{6}$

$RT~=~\Large\boxed{17}$

Step-by-step explanation:

Given information

$RS=2x-8$

$ST=11$

$RT=x+10$

Derived expression from the given information

Presumably, I think this is a combination of segments

$RS+ST=RT$

Substitute values into the given expression

$(2x-8)+(11)=(x+10)$

Combine like terms

The following is the expression

$\Large\boxed{2x+3=x+10}$

Subtract 3 on both sides

$2x+3-3=x+10-3$

$2x=x+7$

Subtract x on both sides

$2x-x=x+7-x$

$\Large\boxed{x=7}$

Substitute the x value into corresponding expressions to determine the final value

$RS=2x-8=2(7)-8=14-8=\Large\boxed{6}$

$RT=x+10=(7)+10=\Large\boxed{17}$

Hope this helps!! :)

Point P is on line segment OQ. Given OQ = 4x + 2, PQ = 4x – 10, and

Verizon [17]

Answer:

Step-by-step explanation:

Since, Point P is on line segment OQ.

$\therefore O - P - Q\\\\\therefore OP + PQ = OQ\\\\\therefore 3x - 3 + 4x - 10 = 4x + 2\\\\\therefore 7x - 13 = 4x + 2\\\\\therefore 7x - 4x = 2 + 13\\\\\therefore 3x = 15\\\\\therefore x = \frac{15}{3}\\\\\huge \purple {\therefore x = 5} \\\\OQ = 4x + 2 = 4\times 5 + 2 = 20 + 2\\\\\huge \orange {\boxed {OQ = 22}}$
