Solve the equation systems or set the values x = 1.8 and y = -0.9 on the equation and check the equality.

A.

6x - 5y = 15

L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3

R = 15

L ≈ R

x + 2y = 0

L = 1.8 + 2(-0.9) = 1.8 - 1.8 = 0

L = R

B.

4x + 5y = 8

L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7

R = 8

L ≠ R

C.

x - 2y = 4

L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6

R = 4

L ≈ R

4x + 5y = 8

L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7

R = 8

L ≠ R

D.

6x - 5y = 15

L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3

R = 15

L ≈ R

x - 2y = 4

L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6

R = 4

L ≈ R

We have two probability solutions: A and D.

But I think, Your answer is A.

A.


6x - 5y = 15


L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3


R = 15


L ≈ R


x + 2y = 0


L = 1.8 + 2(-0.9) = 1.8 - 1.8 = 0


L = R


B.


4x + 5y = 8


L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7


R = 8


L ≠ R


C.


x - 2y = 4


L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6


R = 4


L ≈ R


4x + 5y = 8


L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7


R = 8


L ≠ R


D.


6x - 5y = 15


L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3


R = 15


L ≈ R


x - 2y = 4


L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6


R = 4


L ≈ R

Yeah so your answer is gonna be

<em>A.</em>

Anyone know how to do this with a explanation ?
storchak [24]

Answer:

30 degrees

Step-by-step explanation:

Since we know that all triangles equal 180 degrees, we can add the 2 given angles and subtract that from 180 to find the remaining angle.

90+60=150

180-150=30 degrees
