Answer:
C. - X = 5 units
Step-by-step explanation:
We need to solve for x from the given figure.
In ΔADB and ΔCDB
∠ABD=∠BCD (Corresponding angle of two right triangle)
∠ADB=∠CDB (Each 90°)
∴ ΔADB ≈ ΔCDB By AA similarity
If two triangles are similar then ratio of their corresponding height are same.
Substitute the value of side into the expression
Cross multiply and solve for x
x can't be negative because side of triangle is positive.
Hence, The value of x is 5 units.
Answer:
x = -4 ; y = 1
Step-by-step explanation:
2x + 6y = -2 --------(i)
-x + 2y = 6 --------(ii)
2x + 6y = -2
(ii)*2 <u> -2x + 4y = 12</u>
add; 10y = 10
y = 10/10
y = 1
Substitute y in (i)
2x + 6*1 = -2
2x +6= -2
2x = -2-6
2x = -8
x = -8/2
x = -4
