Explain the difference between AAS congruence and ASA

1 answer:

7 0

ASA - If two pairs of angles of two triangles are equal in measurement, and the included sides are equal in length, then the triangles are congruent.

AAS - If two pairs of angles of two triangles are equal in measurement, and a pair of corresponding non-included sides are equal in length, then the triangles are congruent.

What is the solution of the equation x2 + 8x + 5 = 0?

Setler79 [48]

Answer:

x = -0.683 (3dp)

x = -7.317 (3dp)

Step-by-step explanation:

Step 1: Apply the quadratic formula

(-b±( $\sqrt{b^{2}-4ac}$ )) / 2a

a = 1 (x²)

b = 8 (8x)

c = 5 (5)

(-8±( $\sqrt{8^{2}-4 x 1 x 5}$ )) / 2 x 1

Step 2: Simplify

(-8±( $\sqrt{44}$ )) / 2

Step 3: Solve

You need to replace the ± with first a + and then a -.

(-8+( $\sqrt{44}$ )) / 2 = -0.683 (3dp) = x

(-8-( $\sqrt{44}$ )) / 2 = -7.317 (3dp) = x

Hope this helps!

How do I solve this problem

Alex73 [517]

Find a common denominator between the two (this case it would be 18) and bring the fractions up, so 10/9 would be 20/18, and 3/2 would be 27/18. Then, multiply across, and simplify to lowest terms.

Anna11 [10]

Answer: 265.9167 square inches (rounded)

Step-by-step explanation:

Shoot, okay if this is wrong, shame on me:

All you do is find the areas of each rectangle and add them together.

(12 × 13 1/3) + (10 1/4 x 10 1/3) = 265.9167 (rounded) square inches. Or as a fraction: 3191/12
