Answer:
No.
Step-by-step explanation:
Sam is incorrect because if you look at the original problem, you'll see that he has missed the negative sign!
90 / 9 does equal 10, but 90 / -9 equals -10.
The only way to get a positive answer is if both the divisor and dividend are positive or if they are both negative.
Thus, the correct answer should be -10.
Answer: B. and E.
Step-by-step explanation:
B. is correct because m∠2 = m∠6 are alternate interior angles and alternate interior angles formed by parallel lines and a transversal are congruent.
E. x= 120°
m∠2 = m∠6=75°
∠6+x-15=180°
75°+x-15°=180°
60°+x=180°
x=180°-60°
x=120°
286.9 is the Answer I did the math
No.
Perpendicular lines are lines that intersect at a 90° angle.
If two lines are perpendicular, they create four 90° angles.
However, for two lines to intersect, they do not necessarily have to intersect at a 90° angle.
<em>All roses are flowers, but not all flowers are roses.</em>
<em>All perpendicular lines are intersecting lines, but not all intersecting lines are perpendicular.</em>
