Answer:

The value of x = 10.

Step-by-step explanation:

From the given triangle,

  • The value of angle M = (3x + 28)°
  • The value of angle K = (5x - 18)°
  • The value of angle L = 90°

We know that the sum of a triangle is 180°.

i.e.

K + L + M = 180°

(5x - 18)° + 90° + (3x + 28)° = 180°

5x-18+90+3x+28=180

5x+3x-18+90+28=180

8x-18+90+28=180

8x+100=180

8x=80

\frac{8x}{8}=\frac{80}{8}

x=10

Therefore, the value of x = 10

Find the missing length indicated. <br> Your answer
Naddika [18.5K]

Answer:

x = 12

Step-by-step explanation:

For the middle size triangle

short leg = x

long leg = (25 - 9) = 16

ratio = x/16

For the small triangle

short leg = 9

long leg = x

ratio = 9/x

Similar triangles are proportional so

Set the ratios equal

x/16 = 9/x

Cross multiply

x² = 144

Take the square root of both sides

x = 12

What is the slope of the line passing through points (-8,5) (-8,-8)
vladimir1956 [14]

Answer:

<h3>Undefined.</h3>

Step-by-step explanation:

<u><em>SLOPE FORMULA:</em></u>

\rightarrow \displaystyle \mathsf{\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}  }}

y₂= (-8)

y₁=5

x₂=(-8)

x₁=(-8)

Solve & simplify.

\displaystyle \mathsf{\frac{(-8)-5}{(-8)-(-8)}=\frac{-13}{0}=\boxed{\mathsf{0}}  }}

Therefore, the slope is undefined.

IF x+y=5 and x-2y=-4 find the value of x and y​
Serggg [28]

Answer:

x = 2, y = 3

Step-by-step explanation:

x + y = 5

Shift y to the other side and change to (-y).

x = 5 - y  --- Equation 1

x - 2y = -4 --- Equation 2

Substitute x = 5 - y into Equation 2:

x - 2y = -4

5 - y - 2y = -4

Shift 5 to the other side and change to (-5).

-y - 2y = -4 - 5

Evaluate like terms.

-3y = -9

Divide both sides by -3.

y = -9 ÷ -3

y = 3

Substitute y = 3 into Equation 1:

x = 5 - y

x = 5 - 3

x = 2
