Answer:

75 degrees

Step-by-step explanation:

all added up is 180 on every triangle. 70+35=105. 180-105=75

B. 75°

Because All triangles add up to 180°. Therefore, 70°+35°=105°. From there, 180°-105°=75°.

Because when you multiply by 10, it adds a zero to the end of the number, like 12*10 = 120, so vise versa for dividing

Dont even know where to start

zalisa [80]

Answer:

$\displaystyle M = ( 3,1 )$

Step-by-step explanation:

we are given the endpoint i.e P and Q of a line segment

we want to figure out the Midpoint of the Line segment

in order to do so we can use Midpoint formula given by

$\displaystyle M = \bigg( \frac{ x_{1} + x_{2} }{2} , \frac{ y_{1} + y_{2}}{2} \bigg)$

so let

$x_1=-2\\x_2=8\\y_1=-2\\y_2=4$

substitute

$\displaystyle M = \bigg( \frac{ - 2 + 8}{2} , \frac{ - 2 + 4}{2} \bigg)$

simplify addition:

$\displaystyle M = \bigg( \frac{ 6}{2} , \frac{ 2}{2} \bigg)$

simplify division:

$\displaystyle M = ( 3,1 )$

hence,

the Midpoint of the line segment is (3,1)

without using a calculator decide which option is better value for money: 300g Jelly beans $5.80 or 500g Jelly beans $9.90

yarga [219]

Answer:

500g Jelly beans $9.90

Step-by-step explanation:

To know the values.

Let's know how much a gram will cost in each case

300g Jelly beans $5.80

1g = 5.8/300

1 g = 0.01933

500g Jelly beans $9.90

1g = 9.9/500

1g =0.0198

It's obvious that the second one has more value placed on it as it cost more per gram

Find the value of x. Round to the nearest tenth.! PLEASE HELPP I’ve been stuck on it for HOURS!

barxatty [35]

Answer

63.2 degrees

Step-by-step explanation:

Using law of cosines: 19^2=8^2+14^2-2(8)(14) cos (x)

361=64+196-224 cos(x)

361=260-224cos(x)

101=224cos(x)

divide both sides by 224, which gets you (rounded to 4th decimal place) 0.4509. do inverse cos which gets you 63.2

A square is folded into half to form a rectangle. the perimeter of the rectangle is 36cm. calculate the area of a square

zhannawk [14.2K]

Answer:

Let the measure of each side of the square be " x " cm.

then ,

area of square = x²

After we folded the square into a rectangle ,

length of rectangle = x

breadth of rectangle = x/2

perimeter of rectangle = 36 cm

$x + \frac{x}{2} + x + \frac{x}{2} = 36 \\ \\ \frac{2x + x + 2x + x}{2} = 36 \\ \\ \frac{6x}{2} = 36 \\ \\ 6x = 36 \times 2 \\ \\ 6x = 72 \\ \\ 6x = \cancel{\frac{72}{6} } = 12cm$

hence ,

side of square = 12 cm

therefore ,

area of square = 12 × 12 = 144 cm²

hope helpful~
