Answer:

The congruence statement tells you that both angle B and angle E are equal, since the triangles are identical!

Step-by-step explanation:

We want to set the equations equal to each other.

2x+31=7x-24

We need to isolate our variable, which is X.

1. Add 24 to both sides.

New Equation: 2x+55=7x

2. Subtract 2x from both sides.

New Equation: 55=5x

3. Divide by 5 from both sides so X is alone!

New Equation: x=11

Enough said! :D

What method(s) would you choose to solve the equation: x2 + 2x - 6 = 0

Nataly_w [17]

Complete the square since can't factor
2/2=1
add 1 to both sides
x²+2x+1-6=1
factor perfect square
(x+1)²-6=1
add 6 to both sides
(x+1)²=7
sqrt both sides
x+1=+/-√7
minus 1 both sides
x=-1+/-√7

so x=-1+√7 or x=-1-√7

If j is 21 inches, k is 12 inches, and ∠M measures 62°, then find m using the Law of Cosines. Round your answer to the nearest t

Naily [24]

Answer:

$m=18.7\ in$

Step-by-step explanation:

see the attached figure to better understand the problem

Applying the law of cosines

$m^2=j^2+k^2-2(j)(k)cos(M)$

substitute the given values

$m^2=21^2+12^2-2(21)(12)cos(62^o)$

$m^2=348.39\\m=18.7\ in$
