60 degrees or C. Since the missing angle is the opposite of the 120 degree angle, 180 degrees minus(since that is the amount of degrees in a straight line, and a circle contains 360 degrees) the other angle gives you your answer.

Answer:

the measure of the missing angle is 60°

Step-by-step explanation:

GIVEN : j || k

solution :

We will use the property of linear pairs


120° + ∠1 = 180° (sum of linear pairs is 180°)


⇒ ∠1 = 180°- 120°


⇒∠1 = 60°

now since j || k

So, we can use corresponding angle properties

So, ∠? = ∠1 (corresponding angles are equal)

⇒∠? = ∠1  = 60°

Thus ? = 60°

Answer:

a) 25/324

b) 1/4

c) 1/3

Step-by-step explanation:

a) [⅓A + ⅓B]² = (⅓)²[A + B]²

= (1/9) [½ + ⅓]²

= (1/9)(⅚)²

= (1/9)(25/36)

= 25/324

b) ½ × ½ = ¼

c) (½ × ⅓) + (⅓ × ½) = 2 × ⅙ = ⅓

3x + 3<br> X + 8<br> What is the perimeter of each polygon?
Ganezh [65]

Answer:

D. 60

Step-by-step explanation:

4(3x + 3) = 5(x + 8)       12(4) + 12         5(4) + 40

12x + 12 = 5x + 40        48 + 12               20 + 40

-5x          -5x                   60                        60

7x + 12 = 40

 -12        -12

7x = 28

x = 4

A recipe says to use 3cups of flour to make 48 cookies. What is a constant of proportionality that related the number of cookies
MA_775_DIABLO [31]

Answer:

y=16 x=1

Step-by-step explanation:

For this one, we need to find the unit rate, which means how many cookies we can make using 1 cup of flour. To do that, we need to divide both the flour and the cookies by 3 to get 3/3=1 and 48/3=16. So the total amount of cookies made with one cup of flour is 16. So the constant proportionality is 16,1.
