8. Perform the indicated operations; reduce the answer to lowest terms.
a. 3/10 + 6/10
b. 1/3+1/4+1/6
c. 5/6 - 3/6
d. 2/3 -3/7
e. 4/10 x 6/10
f. 1/6x 6/15
g. 1/8 divided by 4/9
h. 1/5 divided by 3/4

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

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°
