Hello!
The equivalent measurement should be C. 13.1 ft, because 4 meters are equivalent to 13 ft 1.48 in.
Answer: 57°
Given : In triangle PQR, the side PQ is 17, QR is 15, and PR is 14.
We use law of cosine formula


225 = 196 + 289 - 476 cos(P)
225 = 485 - 476 cos (P)
Subtract 485 on both sides
-260 = -476 cos(P)
= cos(P)
P = 
P= 56.89202
So measure of angle P is 57 degrees
Answer:
Lilly, since the angles are the same we can set the equal to each other, that's the "trick" of this problem
Step-by-step explanation:
3x + 50 = 6x - 10
3x + 60 = 6x
60 = 3x
20 = x
see how I got that?
Step One: 7560 ÷ 4 = 1890 Stacks Of Quarters
Step Two: 58 * 1890 = 109,620 Quarters
The Arch is 109,620 quarters high.
