If you use the inverse operation that it subtraction so 12 minus 4 is 8 so if u substitute 8 for x, 8 + 4 is 12
Answer:
Yes, both triangles are congruent to each other by SIDE ANGLE SIDE property of congruence.
Step-by-step explanation:
Two triangles are said to be congruent if and only if they have same corresponding angles and sides.
Now, here
Side 1 = Side 2 (given)
Side 3 = Side 4 (given)
Central angle of triangle 1 = Central angle of triangle 2 (Vertically Opposite)
Hence, by the rule of SIDE ANGLE SIDE (SAS) rule of congruence ,
Triangle 1 ≅ Triangle 2
Answer:
x = 18 cm
Step-by-step explanation:
(4x)^2 = 3(4x)(x+6)
16x^2=3(4x)(x+6)
divide both sides by 4x
4x = 3(x+6)
4x=3x+18
x = 18
