Answer:
17. angle DAB=118º
18. angle DAB=126º
Step-by-step explanation:
The angle A should be 180º-85º-33º(cause the total angle in a triangle is 180º)
So you will get 62º as the angle of A.
And what the question ask is angle of DAB，so again 180º-62º=118º(A straight line is 180º)
Same goes to question 18，use 180º to minus the two angle given，you get 54º ，and then 180ºminus 54º again，the answer is 126º
Answer:
A. -4
Step-by-step explanation:
Slope is rise over run, or y2-y1 / x2-x1.
<u>The slope is A. -4.</u>
Let's see--does that make sense? A slope of four would be pretty steep, and that matches the graph. It also should be negative because the line goes down and to the right, not up and to the right, so -4 makes sense!
