Answer: 47 degrees

Step-by-step explanation:

7x-9=4x+15 because of the vertical angle rule

7x-9=4x+15

3x=24

x= 8

So the angle 7(8)-9 = 47°

Angle JKL is a straight angle. The measure was of MKL is 30. The measurement of angle JkM is x. What is the measure of angle jkm

k0ka [10]

ANSWER

$x=150\degree$

EXPLANATION

The given line JKL is a straight line. The angle on a straight line is 180 degrees.

This implies that the sum of the angles $\begin{gathered} Solve for x in the equation above:[tex]\begin{gathered} x=180-30 \\ x=150\degree \end{gathered}$

That is the value of x.

A circle with radius of 3 cm sits inside a circle with radius of 5 cm. What is the area of the shaded region? Round your final a

DiKsa [7]

Hello!!

So first you need to find the area of the green circle. The formula for finding area for a circle is A = π r2. So the area for the green circle is 28.26 cm. Then you need to find the area of the blue circle. (Using the same formula) which would be 78.5. Then you subtract the value of the green circle to get the value of the shaded region which then your final answer is 50.24 cm. Hope this helped!!

f a rectangle has a perimeter of 70, a length of x and a width of x - 9, find the value of the length of the rectangle.

trasher [3.6K]

$( x + (x - 9)) \times 2 = 70 \\( 2x - 9) \times2= 70 \\ 4x - 18 = 70 \\ 4x = 70 + 18 = 88$
$x = \frac{88}{4} = 22$
the length is 22

and the width is
22-9=17

good luck

Find the midpoint M of the line segment joining the points A = (-5, 7) and B = (-1, -5).

11111nata11111 [884]

Answer:

M = (-3,1)

Step-by-step explanation:

We need to find the midpoint M of the line segment joining the points

A = (-5,7) and B = (-1, -5)

The mid point of the line segment joining the points (x₁,y₁) and (x₂,y₂) is given by :

$M=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})\\\\M=(\dfrac{-5+(-1)}{2},\dfrac{7+(-5)}{2})\\\\M=(-3,1)$

Hence, the required point is (-3,1).
