Answer:

(11, 13)

Step-by-step explanation:

First Equation: x+y=24

Second Equation: y=x+2

x + (x + 2) = 24

2x + 2 - 2 = 24 - 2

2x/2 = 22/2

x = 11

y = (11) + 2

y = 13

Therefore, the solution to the system is (11, 13)

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

igor_vitrenko [27]

Answer: x= 34

Step-by-step explanation:

Given: The measurement of the angles of the quadrilateral are as

First angle=88°

Second angle=108°

Third angle= 2x°

Forth angle =(3x-6)°

Now, The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

Therefore,

$88+108+2x+(3x-6)=360\\\Rightarrow196+5x-6=360\\\Rightarrow\ 5x=360-190\\\Rightarrow\ x=\frac{170}{5}\\\Rightarrow\ x=34$

GEOMETRY HELP URGENT?

nadezda [96]

Let the centre be O and the line with one end point at the centre and another at the chord CD touches the chord at S .

So CS is the half of 36.7 = 18.35

$sin \angle COS = \frac{18.75}{21.8}$

$\angle COS = sin^{-1}(\frac{18.75}{21.8}) =59.35 degree\\$

Therefore,

$\angle COD =2*59.35 =118.7$

Therefore the measurement of arc CD is 118.7 degree.
