Hi there!

We know that angle MNL is 90 degrees, because a tangent is perpendicular to the radius. Therefore, all we need to do is set up a simple equation.

WORK:
180 = 90 + 71 + x
x = 19

ANSWER:
Angle MLN = 19 degrees

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

<span>NL←→ is tangent to circle M at point N
NL is perpendicular to MN
so
</span> ∠<span>NML = 90

</span><span> ∠MLN = 180 - 90 - 71
</span> ∠MLN = 19

Solve for x:<br> |3x-1|=4

Rashid [163]

Answer:

x = 5/3 x= -1

Step-by-step explanation:

|3x-1|=4

There are two solutions to the absolute value equation, one positive and one negative

3x-1 =4 and 3x-1=-4

Add 1 to each side

3x-1+1 = 4+1 3x-1+1 = -4+1

3x=5 3x = -3

Divide by 3

3x/3 = 5/3 3x/3 = -3/3

x = 5/3 x= -1

. (02.05 MC) Side AB = 5, side BC = 6, side DE = 5, and side EF = 6. What additional information would you need to prove that ΔA

vaieri [72.5K]

Answer:

Side AC is congruent to side DF

Step-by-step explanation:

We are given that

Side AB=5 cm

BC=6 cm

Side DE=5 cm

Side EF= 6cm

We have to find an additional information would need to prove that $\triangle ABC\cong \triangle DEF$ by SSS.

When two triangles are congruent by SSS it means three sides of one triangle are congruent to corresponding sides of other triangle.

We have in triangle ABC and triangle DEF

$AB\cong DE=5 cm$

$BC\cong EF=6 cm$

$AC\cong DF$

Then , $\triangle ABC\cong \triangle$ DEF

Reason: SSS postulates

Answer: Side AC is congruent to side DF
