Answer: B
Step-by-step explanation:
-1 will be your answer. (B)
The answer is 75 degrees. These are supplementary angles so
180-105 = 75
The answer is D) All the steps and the answer are correct. :)
You can just solve using the steps to see if they are right. For example, is -1x17=-17? Yes.
Answer:
x = 3
Step-by-step explanation:
The smaller triangle and larger one are similar, so corresponding sides are proportional.
8/4 = (8 +(x -1))/5
10 = x +7 . . . . . . . . . multiply by 5 and simplify
3 = x . . . . . . . . . subtract 7

<em>Alternate solution</em>
The short segments are also proportional:
(x -1)/(5 -4) = 8/4
x -1 = 2 . . . . simplify
x = 3 . . . . . . add 1
