1) 6*10=60, 6*7=42/2=21, 21+60=81
2) 12*12=144, 12*12=144*3.14=452.16/2=226.08, 144+226.08=370.08
3) 14*5=70, 5*10=50, 70+50=120 (maybe)
4) 6*5=30/2=15, 4*3=12/2=6,15+6=21
5) 6*6=36*3.14=113.04/2=56.52, 5*5=25*3.14=78.5/2=39.25, 56.52+39.25=95.77
if right then give brainliest plz
Answer:
x = 8√5
Step-by-step explanation:
In the figure attached, there are three right angle triangles.
So, by Pythagoras theorem,
y²+ 4² = z²
y² + 16 = z²------(1)
Similarly x² = 16² + y²--------(2)
and (16 + 4)² = x² + z²
20² = x² + z²-------(3)
Now we put the value of z² from equation 1 to equation 3
20² = x² + y² + 16
x² + y² = 400 - 16
x² + y² = 384
y² = 384 - x²------(4)
Now we put the value of y² from equation 4 to equation 2
x² = 16² + 384 - x²
2x² = 256 + 384
2x² = 640
x² = 320
x = 8√5
Therefore x = 8√5 will be the answer.
48 to 60 ? Would be 25% . [(48-60)/48]x100=25% increase .
