Answer 1

Answer:

1. 1=18°, 2=90°

2. 1=85°

3. 1=97°

4. 2=83°

5. 3=49°

6. 1=94°

7. 4=45°

8. 3=65°

9. 2=79°

10. 5=73°

11. 6=147°

12. 1=26°

13. 2=32°

Step-by-step explanation:

1. all angles of a triangle equal 180. 2 is 90 degrees because you can look across to find the symbol. Then you subtract 180 by 72 and 90 to get 18.

2. do the same thing as last time, 180 minus 40 and 55.

3. In order to figure this out, you need to have the angle 2. One you have 83, angles like this, together will add up to 360 if you put 2 of them together. 83×2=166. 360-166=194. 194/2=97.

4. To figure this out, you find the angle across from it because those are always the same. Follow the same process to subtract 39 and 58 from 180 to get 83.

5.Now that you have the angle 2 you can figure this one out as well, again, follow the process of subtracting the two opposite angles from 180 to get 49.

(This is taking really long to explain so if you have questions just ask.)

Find the area in the pic please!!

Answers

Answer:

Area = 970 ft²

Step-by-step explanation:

The shape is composed of a square and a triangle.

Therefore:

Area of the shape = area of square + area of triangle

✔️Area of square = s²

s = 20 ft

Area = 20²

Area of square = 400 ft²

✔️Area of triangle = ½*b*h

b = 20 + 9 + 9 = 38 ft

h = 30 ft

Area of triangle = ½*38*30 = 570 ft²

✅Area of the shape = 400 + 570 = 970 ft²

Which comparison of the two equations is accurate?
Equation A: Sqrt x^2 + 3x-6 - Sqrt X+2
Equation B: Sqrt x^2 + 3x-6 = Sqrt x+2
O Both equations have different solutions because the square root of a number is not the same as the cube root of a
number
O Both equations result in different equations after eliminating the radicals, so they have the different solutions.
O Both equations have the same potential solutions, but equation A might have extraneous solutions.

2. A coin purse contains d dimes and q quarters. There are 20 coins in the purse, and the total value of the coins is $4.25. Which system of equations represents this situation?
A {d + q = 4.25
{0.1d + 0.25q = 20

B {d + q = 20
{0.1d + 0.25q = 4.25

C {d + q = 20
{d + q = 4.25

Answers

B. D represents the amount of dimes and q represents the amount of quarters so that equals 20 coins total. 0.25q is the amount of quarters multiples by their cost, when added to 0.1d it equals 4.25.
