Label each pair of triangles with the postulate or theorem that proves the triangles are congruent.

Answers

Answer 1

Answer:

Answer:

We can conclude that Δ GHI ≅ Δ JKL by SAS postulate.

Step-by-step explanation:

Δ GHI and Δ JKL are congruents because:

1. Their sides GH and JK are equal (9 units = 9 units)

2. Their included angles ∠G and ∠J are equal (62° = 62°)

3. Their sides GI and JL are equal (17 units = 17 units)

Now, we can conclude that Δ GHI ≅ Δ JKL by SAS postulate.

What is the value of x?

Answers

Answer:

120

Step-by-step explanation:

Because we know that the line opposite of the right angle is flat, we know that 60 plus x must equal 180. Rewriting this gives us 180 - 60 = x.

Now, we can just solve for x.

x = 120.

What is x2+2x-8=0 by factoring ?

Answers

Answer:

(x+4)(x-2)

Step-by-step explanation:

We need to find two numbers that multiply to -8 and add up to 2. These are 4,-2.

Rewrite the polynomial:

x^2-2x+4x-8

and factor each pair:

x(x-2)+4(x-2) = (x+4)(x-2)
