26.4 because .42 you have to leave the 4 the same since the 2 is not greater than 5.
Answer:
533.33 ft/min
Step-by-step explanation:
We are given that
x=3 feet
y=4 feet
Height of person,h=6 feet

Triangle ABC and A'B'C are similar because all right triangles are similar
By using similarity property








Differentiate w.r.t t



Hence, If the person is 6 feet tall and walks away from the lamp post at a speed of 400 feet per minute then his shadow moving at the rate 533.33 ft/min
Answer:
6: Reason 2 - substitution, Statement 4 - PR congruent to PR, Reason 4 - reflexive property, Reason 5 - AAS
8: Rotation
Step-by-step explanation:
6: Since both of the given angles equal 90°, you can <em>substitute</em> Angle RPT in to make Angle PRQ congruent to Angle RPT. Then, since both triangles share Line PR, <em>PR would be congruent to PR</em> by the <em>reflexive property</em>. And since you know that Angle Q is congruent to Angle T, you can see that Triangle QRP is congruent to Triangle TPR by the <em>AAS theorem</em>.
8: Since the 1st triangle is pointing to the right and the 2nd triangle is pointing downward, this would be a rotation of 90° clockwise (or 90° counterclockwise if the 1st triangle is the one pointing downward)
I don't have 7, sorry.
Also (if you haven't noticed it already), there's a typo in the 1st statement of the proof. Just thought I'd let you know ;)
Answer:
<em>AC=16 inches</em>
Step-by-step explanation:
Given two side lengths of a triangle as x and y (x greater than y), the third side z must satisfy the inequality:
x - y ≤ z ≤ x + y
The side lengths are x=17 and y=10, thus:
17 - 10 ≤ z ≤ 17 + 10
7 ≤ z ≤ 27
The third side must be between 7 and 27 inches. The only choice that satisfies the conditions is AC=16 inches
