Jamal wants to simplify the expression shown below.(  5  +  8  )  −  (  2  ×  4  )what will be the last step jamal will need to complete to simplify the expression? explain how you know.

13-8

Step-by-step explanation:

you use pemdas

parenthesis

exponents

multiplication

division

addition

subtraction

so you would add 5 and 8 because its in parenthesis and multiply 2 and 4. then you would subtract the 8 from the 13

step-by-step explanation:

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°
