Answer:
Step-by-step explanation:
Height of wall = 10ft
Length of ladder = 12ft
Angle of elevation be x
Sin x = opp/hyp
Sin x = wall height/length of ladder
Sin x = 10/12
Sin x = 0.83
X = Sin-¹ (0.83)
X = 56.44°
Answer:
<h2>Leah is actually wrong, because those rectangles are similar.</h2>
Step-by-step explanation:
Remember that similarity is about having proportional sides and congruent angles. When we have congruent sides, then those rectangles are congruent not similar.
In this case, to find the similarity, Leah should compare bases and heights thorugh division, because the ratio between heights and the ratio between bases must be equal. So, let's divide.


As you can observe, both ratios are equal.
Therefore, those rectangles are congruent.
Answer:
t = 20 + q (minutes)
Step-by-step explanation:
The meeting consists of speaking and Question & Answer (Q&A) sessions.
Speaking session = 20 minutes
Q&A session = q minutes
Total number of minutes spent for the two sessions = 20 + q (minutes)
But total number of minutes meeting lasted = t minutes.
Therefore, t = 20 + q (because they both represent the total number of minutes the meeting lasted)
