Answer : The measure of ∠WRS is 25°.

Step-by-step explanation :

As we know that vertically opposite angles are always equal.

In the given figure,

∠VRT = ∠WRS = (5x)°          (Vertically opposite angles)

And we know that the sum of all angle in a straight line is equal to 180°.

So,

∠TSR + ∠WRS = 180°

Given: ∠TSR = (25x + 30)°

∠TSR + ∠WRS = 180°

(25x + 30)° + (5x)° = 180°

30x + 30° = 180°

30x = 180° - 30°

30x = 150°

x = 5°

∠WRS = (5x)° = (5 × 5)°  = 25°  

Therefore, the measure of ∠WRS is 25°.

Answer:

1. (5x - 2) + (2x - 2) + x = 180^{o}

2. m<J = 113^{o}

3. m<K = 44^{o}

4. m<L = 23^{o}

Step-by-step explanation:

Generally, the sum of angles in a triangle = 180^{o}.

So that;

m<J + m<K + m<L = 180^{o}

(5x - 2) + (2x - 2) + x = 180^{o}

5x + 2x + x -2 -2 = 180^{o}

8x - 4 = 180^{o}

8x = 180^{o} + 4

8x = 184

x = \frac{184}{8}

x = 23^{o}

Thus,

m<J = (5x - 2)

       = 5(23) - 2

       = 113^{o}

m<K = (2x -2)

        = 2(23) - 2

        = 44^{o}

m<L = x

       = 23^{o}

Angle 2 is 2x+10 angle 4 is 4x+80 solve for x
Airida [17]

Answer:

15

Step-by-step explanation:

Angle 2 is 2x+10

angle 4 is 4x+80

and from the figure we can understand that when we add these 2 equations

We get

6x+ 90= 180

6x = 180 - 90= 90

6x= 90

x = 90 ÷ 6 = 15

answer = 15
