Help please!!!!!! 12-13 8th grade math!!!

Mathematics
1 answer:
marin [14]4 years ago

Answer:

12.

m∠ACB = 180° - 58° - 78° = 44°

m∠DCE = 180° - 85° - 60° = 35°

m∠BCD = 180° - 44° - 35° = 101°

13.

Base on the picture, we know that:

x° + 2x° + 3x° = 180°

6x°                 = 180°

x°                   =  180° ÷ 6 = 30°

=> m∠K = 2x° = 2 × 30° = 60°

=> m∠L = 3x° = 3 × 30° = 90°

=> m∠KML = x° = 30°

m∠LMN =  60° + 90° = 150°

Pls help asap I’ll mark BRAINLIEST DONT answer if your not sure, this affects my whole grade
Sidana [21]

Answer:

2.5

Step-by-step explanation:

Add up the 5s of the left side first and you will get 25. Then you add up the 5s on the otherside and you will get 10. Subtract the 10 from the 25 to get 15. Finally, divide 15 by 6 to get the weight of each triangle, 2.5

1: 5 x 5 = 25

2: 5 x 2 = 10

3: 25 - 10 = 15

4: 15/6 = 2.5

The weight of each triangle is 2.5

Have an amazing day!

Find the surface area of the net below.
dedylja [7]

Answer:

472 in²

Step-by-step explanation:

This net is made up of 3 identical rectangles and 2 identical triangles.

Area of a rectangle = width x length

Area of a triangle = 1/2 x base x height

<u>Rectangle</u>

  • width = 8 in
  • length = 19 in

<u>Triangle</u>

  • base = 8 in
  • height = 2 in

<u>Surface Area</u>

SA = 3(8 x 19) + 2(0.5 x 8 x 2)

⇒ SA = 456 + 16

⇒ SA = 472 in²
