Answer:
Step-by-step explanation:
length=1 m
base of triangle=10 m
height=5m
volume= 1/2×10×5×1=25 m cube.
slant height l=√(5²+5²)=√50=5√2
slant surface area=2[5√2×1]=10√2
area of front and back=2×1/2(10×5)=50
total surface area=50+10√2≈50+14.14≈64.14 m²
Answer:
0.5amps
Step-by-step explanation:
I is inversely proportional to resistance
I = k/R
k = I/ R
k = 20/5
k = 4
This means that, I = 4/R
So, when R = 8ohms,
I = 4/8
=0.5amps
4.2 because it has a box around the corner that makes it whole

Answer:
Step-by-step explanation:
in a right angled triangle angles given are 45,90
Then third angle is also 45 °
as two angles are 45° each.
Then sides are also equal.
Let the equal sides be each =x
then hypotenuse=√(x²+x²)=√(2x²)=x√2
sin 45°=x/(x√2)=1/√2
