Answer:

∠A = 115°

∠B = 65°

∠C = 115°

∠D = 65°

Step-by-step explanation:

The figure given is of parallelogram.

We need to find measure of each interior angle.

We are given:

∠A = (2x-15)°

∠B = x°

∠C = (2x-15)°

∠D = x°

We need to find measure of ∠A , ∠B, ∠C, ∠D

We know that sum of all angles of parallelogram = 360°

So, we can write: ∠A +∠B+ ∠C+ ∠D = 360°

Now putting their values and finding value of x first:

[tex]2x-15+x+2x-15+x=360\\Combining\:like\:terms:\\2x+x+2x+x-15-15=360\\6x-30=360\\6x=360+30\\6x=390\\x=\frac{390}{6}\\x=65[/tex]

So, we get x= 65

Now finding measure of each angle:

∠A = (2x-15)° = 2(65)-15 = 130-15 = 115°

∠B = x° = 65°

∠C = (2x-15)° = 2(65)-15 = 130-15 = 115°

∠D = x°= 65°

Answer is:

∠A = 115°

∠B = 65°

∠C = 115°

∠D = 65°

Answers

Answer:

12,180g

Step-by-step explanation:

3x7=21

21x580g=12,180g

12.18 kilograms

she used 580 grams each day for each day of the week. so first do 580 X 7 =4060. then multiply 4060 by 3 because it was for three weeks. you then have 12180 grams. to go from grams to kilograms you need to divide the grams by 1000. so 12180/1000=12.18 :) i hope this helped

Answers

Answer:

For the first: [tex]x=-23[/tex] and [tex]x=17[/tex]

For the second: [tex]x=5[/tex]

Step-by-step explanation:

Answer:

x=17 for the first and x=5 for the second.

Step-by-step explanation:

First picture

Opposite angles of two intersecting lines are equal.

So the angle opposite the 100 degree angle on line c is also 100.

Since a, b, and c are all parallel, the angles made by the intersecting line r, are also all equal (these are corresponding angles).

So 5x + 15 = 100

5x = 85

x = 17

Second picture

Adjacent angles add up to 180 degrees. So the angle opposite 52 is 180-52=128.

[tex]2^{2x-3}=128\\\\2x-3 = 7\\2x = 10\\x=5[/tex]

square root of 9 multiplied by square root of 180

Answers

Square root of 9 is 3 square root of 180 is 13.416roundes 3x13.416 is 40.248

Answer:

18√5

Step-by-step explanation:

√9×√180

from √9 we get 3 cause 3² is 9.

from 180 we get 6√5 because √36×5 is √180.

we took 36 out because it gives us a whole number if we square root it.

So √36×5 is 6√5 , because the square root of 36 is 6

then we multiply 3 and 6√5.

3×6 is 18 so we put 18 and put the √5 behind it.
