1) Answer: x = 9

<u>Step-by-step explanation:</u>

Same Side Interior Angles are supplementary

15 + 5x + 14x - 6 = 180

19x + 9 = 180

19x = 171

x = 9

***************************************************************

2) Answer: x = 9

<u>Step-by-step explanation:</u>

Corresponding Angles are congruent

13x - 7 = 11x + 11

2x = 18

x = 9

***************************************************************

3) Answer: x = -10

<u>Step-by-step explanation:</u>

Alternating Interior Angles are congruent

90 = x + 100

-10 = x

***************************************************************

3) Answer: x = 7

<u>Step-by-step explanation:</u>

Alternating Exterior Angles are congruent

17x + 1 = 120

17x = 119

  x = 7

suppose a triangle has two sides of length 42 and 35 and that the angle.between these two sides is 120° what is the length of th
pickupchik [31]

Answer:

The length of the third side of the triangle is 7\sqrt{91}\ units

Step-by-step explanation:

Let

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

we know that

Applying the law of cosines

c^2=a^2+b^2-2(a)(b)cos(C)

we have

a=42\ units\\b=35\ units\\C=120^o

substitute the given values

c^2=42^2+35^2-2(42)(35)cos(120^o)

c^2=2,989-2,940cos(120^o)

c^2=4,459\\c=\sqrt{4,459}\ units\\c=7\sqrt{91}\ units
