The answer is B, 57 degrees. You can tell angle C is 57 degrees since 180-123 is 57 and both angles add up to 180 on a straight line. Then since the lines are parallel, angle a is 55 degrees because of alternate interior angle theorem. Then, a triangle’s angles add up to 180 so to figure out angle d, you do: 180- (55 + 57) which gives you 68. Since 55 + angle b + angle d = 180, you have to do 180 - (68+55) = 57 degrees. Hope this helps!
Answer:
we would need to know want some of the variables mean
Step-by-step explanation:
<span>a difference of squares
</span>a^2<span> – b^</span>2<span> = (a + b)(a – b)
</span>in this case
<span>(–7x + 4)(–7x – 4)
answer
</span><span>(–7x + 4)(–7x – 4)</span>
Answer:
Simple it would be 76x - 1 whatever that is, and 72x + 3 which u shuld get like uh 75x, and 75x again on both so its 75x
