Answer:

Step-by-step explanation:

Let the number = x

7x + 1 = 5x + 25 Subtract 5x from both sides.

7x - 5x + 1 = 5x - 5x + 25 Combine

2x + 1 = 25 Subtract 1 from both sides.

2x + 1 - 1 = 25-1 Combine

2x = 24 Divide by 2

2x/2 = 24/2

x = 12

The measures angles of hexagon are 4x, 5x, 6x, 7x, 8x and 9x. calculate the size of the largest angle.

ankoles [38]

Answer:

rounded to the nearest whole number = 166

Step-by-step explanation:

Add all of the angles together, to get 39x. In a hexagon, all the angles add up to 720. Divide 720 by 39 to get x, then multiply x by 9, as that is the largest angle to get an answer rounded to the nearest whole number of 166.

a circle with a radius of 1 cm sits inside a 3cm x 3cm rectangle. What is the area of the shaded region (the rectangle is shaded

masha68 [24]

Answer:

The area of the shaded region is $5.86\ cm^{2}$

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the rectangle minus the area of the circle

The rectangle is a square

$A=b^{2} -\pi r^{2}$

we have

$b=3\ cm$

$r=1\ cm$

assume

$\pi =3.14$

substitute the values

$A=3^{2} -(3.14)(1)^{2}$

$A=5.86\ cm^{2}$

Right triangle ABC has three sides with lengths AB= 119, BC = 169, CA= 120. Find the value of cos C. hint: draw and label the tr

GenaCL600 [577]

Answer:

$\cos(C)=\frac{120}{169}$

Step-by-step explanation:

The triangle is shown in the attachment.

Recall that;

$\cos(C)=\frac{Adjacent}{Hypotenuse}$

This implies that;

$\cos(C)=\frac{|AC|}{|BC|}$

We substitute the values into the ratio to obtain

$\cos(C)=\frac{120}{169}$
