6.

Since the angle is connected to a straight line, it would be equal to 180.

22+x=180 (where the missing angle is x)

Subtract 22 from both sides.

x= 158

7. Those angles are congruent. They would be equal to each other.

84=4x

Divide both sides by 4.

x=21

8. Yes. The angle that is opposite it is congruent and is 50 degrees.

38<50 50 is greater than 38.

I hope this helps!

Answer:

of Example 6

5 and 14

Step-by-step explanation:

IN EXAMPLE 6

Opposite angles are equal so you equate the first one like this

3x + 20 = 10x - 15

15 + 20 = 7x

35/7 = x

x = 5

In next question b

It is a straight line thus it's 180°

so 4n + 22 +8n -10 = 180

12n + 12 = 180

12n = 180 - 12

n =168÷ 12

n = 14

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q?

lutik1710 [3]

<h3>Answer: Choice C</h3>

cos(a - b) = cos(a)cos(b) + sin(a)sin(b)

In this case, we'd have a = 180 and b = q, so,

cos(a-b) = cos(a)cos(b) + sin(a)sin(b)

cos(180 - q) = cos(180)cos(q) + sin(180)sin(q)

cos(180 - q) = -1*cos(q) + 0*sin(q)

cos(180 - q) = -cos(q) + 0

cos(180 - q) = -cos(q)
