In the diagram, AngleTRV ≅ AngleVRW. 2 lines intersect. A line with points T, R, W intersects a line with points S, R, V at point R.
What is the measure of AngleSRT?

mAngleSRT = ___ degrees

The measure of angle TRV is 130° ⇒ last answer

Step-by-step explanation:

* According to the attached graph

- Line TRW intersects line SRV at point R

- The measure of angle VRT is (2x + 10)°

- The measure of angle VRW is (x - 10)°

- We need to find measure of angle TRV

- From the attached figure

∵ T , R , W lie on the same line

∴ ∠TRW is a straight angle

- The measure of the straight angle is 180°

∴ m∠TRW = 180°

∵ ∠TRW contains ∠VRT and ∠VRW

∴ m∠VRT + m∠VRW = m∠TRW

∴ m∠VRT + m∠VRW = 180°

∵ m∠VRT = (2x + 10)°

∵ m∠VRW is (x - 10)°

∴ 2x + 10 + x - 10 = 180

- Add like terms

∴ 3x = 180

- Divide both sides by 3

∴ x = 60

∵ m∠TRV = (2x + 10)°

- Substitute x by 60

∴  m∠TRV = 2(60) + 10 = 120 + 10 = 130°

∴ The measure of angle TRV is 130°

Option C. is the correct option.

Step-by-step explanation:

The given line in the graph passes through two points (0, 3) and (3, 7).

We have to find the equation of the line.

Since y = mx + c is the standard equation of a line

where m = slope of the line

c = y - intercept

Slope of a line m =

Now we put the values of x and y to find the slope of this line.

m =

Since (0, 3) passes through the line

3 = 0 + c

c = 3

Equation of the line will be

Option C. is the answer.
