For solving of the area of a square pyramid, we can use the formula below:
A=a²+2a sqrt (a²/4 +h²)
where s for the slant height, r for the a/2, where a is the side length and h for the height
Substitute the values,
A=40²+(2*40) SQRT (40²/4 +21²)
A=3920
The answer is 3920 for the area of the square pyramid.
Answer:
in triangle PQR, <P - <Q = 20 degrees, <Q - <R = 50 degrees, find <P, <Q, <R
Q = 30, R = 80, P = 50
Step-by-step explanation:
in triangle PQR, <P - <Q = 20 degrees, <Q - <R = 50 degrees, find <P, <Q, <R
R = Q
+50, 80=30+50
P = Q
+
20, 50=30+20
Q = 30, R = 80, P = 50

i dont know though its not homewrok
Step-by-step explanation:
You add them together and subtract 1 because the total amount stays the same throughout the entire problem and you have to find the amount of water in the glass that is not full when the other glass is full. 10/12 + 8/15 = 50/60 + 32/60 = 82/60. 82/60 - 60/60 = 22/60, which simplifies to 11/30.
um 600?? I'm sorry if that's wrong
