Could 8.8 cm, 8.0 cm and 8.8 cm be the side lengths of a triangle?
Alinara [238K]

Answer:

yes it is possible to have a triangle with 8.8 cm, 8.0 cm and 8.8 cm.

Step-by-step explanation:

Condition on sides of triangle:

  • The triangle inequality states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
  • It is not possible to have sum to be less than the length of the third side.
  • A triangle with three given positive side lengths exists if and only if those side lengths satisfy the given condition
  • Let a, b and c be three sides of triangle.

a + b > c\\a+c>b\\b+c>a

Here, we are given that a = 8.8 cm, b = 8.0 cm, c = 8.8 cm

We check for the triangular inequality:

1.~8.8 + 8.0 > 8.8\\16.8>8.8\\2.~8.8+8.8>8.0\\17.6>8.0\\3.~8.0+8.8>8.8\\16.8>8.8

Thus, yes it is possible to have a triangle with given measurements.

Can you find the angle CDE​
PolarNik [594]

Answer:

∠CDE = 14°

Step-by-step explanation:

Since CE is extended to point F then ∠FED is an external angle of the triangle

The external angle of a triangle is equal to the sum of the 2 opposite interior angles, that is

∠FED = ∠ECD + ∠CDE ← substitute values

4x + 5 = x + 8 + x + 9, that is

4x + 5 = 2x + 17 ( subtract 2x from both sides )

2x + 5 = 17 ( subtract 5 from both sides )

2x = 12 ( divide both sides by 2 )

x = 6

Hence

∠CDE = x + 8 = 6 + 8 = 14°

Find ∠ABD if ∠ABC = 121° in the given figure.
siniylev [52]

Answer:

81°

Step-by-step explanation:

∠ABC= 121°

  • 4x+21+3x-5=121
  • 7x+16=121
  • 7x= 105
  • x=105/7
  • x=15°

∠ABD= 4*15°+21°= 81°
