Answer:

check: 50+160+130+20 = 360

50:160 = 5 : 16

Step-by-step explanation:et the smaller of the unknown angles be 5x and the larger of the two be 16x

so 130+20+5x+16x = 360

21x = 210

x = 10

so the two missing angles are 50° and 160°

check: 50+160+130+20 = 360

50:160 = 5 : 16

anzhelika [568]

Answer:

Spiders=8

Ants=12

Step-by-step explanation:

Spider(s)=8 legs

Ants(a)=6 legs

Total legs=136

Total heads=20

8s+6a=136 (1)

s+a=20 (2)

From (2)

s=20-a

Substitute 20-a into (1)

8s+6a=136

8(20-a)+6a=136

160-8a+6a=136

160-2a=136

-2a=136-160

-2a=-24

a= -24/-2

a=12

Substitute a=12 into (2)

s+a=20

s+12=20

s=20-12

s=8

HELPPPPPPPPP PLEASE!!! :(
erastovalidia [21]

Answer:

x = 25

Step-by-step explanation:

Given:

  • ∠A = ∠B    (Vertically opposite angles)
  • ∠A = (7x - 8)°
  • ∠B = (6x + 17)°

Since ∠A is equivalent to ∠B...

\implies (7x - 8)= (6x + 17)

Open the parenthesis:

\implies 7x - 8= 6x + 17

Add 8 both sides:

\implies 7x - 8 + 8= 6x + 17 + 8

Simplify both sides:

\implies 7x = 6x + 25

Subtract 6x both sides:

\implies 7x - 6x = 6x - 6x + 25

Simplify both sides:

\implies x = 25

Y=-3x+5 <br> 5x-4y=-3<br> Trying to solve this problem
rodikova [14]
Your answer would be y= 5x/-4 - 3/-4 because you’ll move 5x to the other side of the equal sign then divide -4 to get y by itself
