−3 2/3⋅(−2 1/4) ?

A −8 1/4
B −6 1/6
C 6 1/6
D 8 1/4

49

Step-by-step explanation:

so let explain

you first have to make the fractions into whole numbers the way you do that is by

1) multiply the 3 times -3

2) then add 2

3) = -7

The next one you do the same

4 times -2

plus 1 =-7

so then this what the equation would look like

-7(-7)

so you multiply the 7 and get

49

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
