Sardis was drawing a triangle. The first segment he drew was 10 centimeters. The 2nd side he drew was 12 centimeters. How long w
HACTEHA [7]

Answer:

see the explanation

Step-by-step explanation:

we know that

The<u><em> Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Applying the triangle inequality theorem

Let

c ----> the measure of the length of the third side

1) 10+12 > c

22 > c\\c < 22 cm

2) c+10>12

c > 12-10\\c >2 cm

so

The solution for the length of the third side is the interval (2,22)

All real numbers greater than 2 centimeters and less than 22 centimeters

Svetradugi [14.3K]

Answer:

B

Step-by-step explanation:

Using the rule of exponents

a^{-m} = \frac{1}{a^{m} }

Given

y = 12 × 3^{x} ← substitute x = - 2 into the expression

y = 12 × 3^{-2} = 12 × \frac{1}{3^{2} } = 12 × \frac{1}{9} = \frac{12}{9} = \frac{4}{3} → B

If x=3+5i and y=-2+7i, what is y-x?
faust18 [17]

Answer:

-5+2i

Step-by-step explanation:

x = 3 + 5i , y = - 2 + 7i

y - x = - 2 + 7i - (3 + 5i)

   = -2 + 7i - 3 - 5i

Collect like terms

-2 -3 + 7i - 5i

-5 + 2i

Therefore y-x = -5 + 2i

Murljashka [212]

Answer:

m∠ABC = 130.4°

Step-by-step explanation:

Angle Bisector: The line that divides the angle into <u>two equal parts</u>.

If BD bisects ∠ABC then:

⇒ ∠ABD = ∠DBC

Given m∠ABD = 65.2° then:

⇒ ∠DBC = 65.2°

Therefore:

⇒ m∠ABC = m∠ABD + m∠DBC

⇒ m∠ABC = 65.2° + 65.2°

⇒ m∠ABC = 130.4°
