Explanation:
Finish the Given statement, make use of the relationships of angles and parallel lines, then finish the algebra.

2. m∠6 = (1/8)m∠4 . . . . Given
3. m∠6 + m∠4 = 180° . . . . 3. same-side interior angles are supplementary
4. m∠6 + 8·m∠6 = 180° . . . . 4. Substitution (from 2, above: 8·m∠6 = m∠4)
Here is the "algebra" that gets you to line 5:
4a. 9m∠6 = 180° . . . collect terms
4b. m∠6 = 20° . . . . . divide by 9
4c. m∠4 = 8·20° = 160° . . . use the same relation as in step 4
5. m∠6 = 20°, m∠4 = 160° . . . . Algebra
Answer:
A
Step-by-step explanation:
the angle is 115.6
Hope this helps
Answer:
n = 250
Step-by-step explanation:
To express the ratio, the quantities must have the same measures
2 cm : 5 m
= 2 cm : 500 cm [ 1 m = 100 cm ]
Divide both parts by 2
= 1 : 250 → with n = 250
Let's first write down all the information given in <em>y = mx + b</em> form. Notice that x-intercept means that <em>y = 0</em> at that point. <em>b</em> is not given, so:
Let's solve for b:
Now we have the equation:
We can plug in every option given to see which choice makes it true:
<u>(0, 30)</u>
<u>(5, 15)</u>
<u>(10, 10)</u>
<u>(-5, 60)</u>
Therefore, choice D or <u><em>(-5, 60)</em></u> is your answer. Hope I could help! :)
