The triangles shown below must be congruent. right awnsers only .

False

Step-by-step explanation:

Properties of congruent triangle :

SSS -"side, side, side" and means that we have two triangles with all three sides equal.

ASA- "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal.

SAS -"side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal.

AAS -"angle, angle, side" and means that we have two triangles where we know two angles and the non-included side are equal.

Since the given triangles does not satisfy any property

So, the given triangles are not congruent.

So, Option B is true

Hence False

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

answer: do we write it
