Answer::.x=6,y=2
3x - 5y = 8......(1)
X - 5y = - 4......(2)
subtracting equation 2 from 1 we get
Step-by-step explanation:
3x - 5y = 8
X - 5y = - 4
-
------------------
2x=12
x=12/2=6
multiplying equation 2 by3 weget
3x-15y=-12........(3)
subtracting equation 1from 3
3x-15y=-12
3x-5y=8
-
------------------
-10y=-12-8
y=-20/-10=2
Hello!
The angle is a right angle, which measures 90°.
3x + x = 4x
Angle = 4x + 10 = 90
Switch that around
90 - 10 = 4x
90 - 10 = 80
80 = 4x
Divide by 4

Answer:
The triangles are congruent by
SSS
Step-by-step explanation:
Given:
First Label the Diagram:
AB ≅ CD
AD ≅ BC
To Prove:
Δ ABC ≅ Δ CDA
Proof:
In Δ ABC and Δ CDA
AB ≅ CD ....……….{Given}
BC ≅ DA …………..{Given}
AC ≅ AC ……….{Reflexive Property}
Δ ABC ≅ Δ CDA ….{ By Side-Side-Side test}
Subtract 5x from both sides, 7x+2=-26, subtract 2 from both sides, 7x=-28, divide both sides by 7, x=-4
