1:120   2: 36

Step-by-step explanation:

1: The interior angle of a hexagon is 4*180/6=120. Double that, and we get 240. x is 360-240=120.

2: The interior angle of a pentagon is 108, 180-108=72, 72/2=36=x

2

Step-by-step explanation:

solve for x (make x on one side and bring all numbers to other side)

multiply 5 into parenthesis

5x+15=25

subtract both side 15

5x=10

divide 5 both side

x=2

[tex]\boxed {\tt 13.75 \ yards}[/tex]

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean Theorem.

[tex]a^2+b^2=c^2[/tex]

where [tex]a[/tex] and [tex]b[/tex] are the legs and [tex]c[/tex] is the hypotenuse.

One of the legs is 10 yards, and the other is unknown. The hypotenuse is 17 yards, because it is the longest side.

[tex]a= 10 \ yd\\b=b\\c= 17 \ yd[/tex]

Substitute the values into the formula.

[tex](10 \ yd)^2+b^2=(17 \ yd)^2[/tex]

Evaluate the exponents.

(10 yd)²= 10 yd * 10 yd = 100 yd²

[tex]100 \ yd^2+b^2= (17 \ yd)^2[/tex]

(17 yd)²= 17 yd * 17 yd=289 yd²

[tex]100 \ yd^2+b^2= 289 \ yd^2[/tex]

Now, solve for b. First, subtract 100 yards squared from both sides of the equation.

[tex]100 \ yd^2-100 \ yd^2+b^2= 289 \ yd^2- 100 \ yd^2[/tex]

[tex]b^2=289\ yd^2-100 \ yd^2[/tex]

[tex]b^2=189 \ yd^2[/tex]

Finally, take the square root of each side of the equation.

[tex]\sqrt{b^2} =\sqrt{189\ yd^2}[/tex]

[tex]b=\sqrt{189 \ yd^2}[/tex]

[tex]b=13.7477271 \ yd[/tex]

Round to the nearest hundredth. The 7 in the thousandth place tells us to round the 4 to a 5.

[tex]b \approx 13.75 \ yd[/tex]

The other side of the garden is about 13.75 yards long.

Step-by-step explanation:

4c = d

c = d/4

The length of image of AB after the dilation is 18 cm

Solution:

Given data:

Length of AB = 9 cm

Scale factor (k) = 2

Length of image of AB = ?

By the definition of scale factor,

[tex]$k=\frac{\text { Length of Dilated image AB }}{\text { Length of original image } \mathrm{AB}}$[/tex]

[tex]$2=\frac{\text { Length of Dilated image AB }}{9}[/tex]

Do cross multiplication, we get

2 × 9 = Length of dilated image of AB

18 = Length of dilated image of AB

Hence the length of image of AB after the dilation is 18 cm.

X = 2

Step-by-step explanation:

5(x+3) = 25

25 / 5 = 5

x + 3 = 5

5 - 3 = x

x = 2
