Note that sin 45 deg = opposite side / hypotenuse.
1 7sqrt(2)
Here, sin 45 deg = ----------- = --------------
sqrt(2) x
Cross multiplying, we get x = 7 [sqrt(2) ]^2 = 7(2) = 14 (answer)
Step-by-step explanation:
do () first
2*1-1
then multiplication
2-1
then subtraction
=1
same reason as above
4 *2 -6
8-6
=2
3/8 cross multiply x/800 8x and 2400 divide both sides by 8 to get 300. 300 is the answer
Answer:
B
Step-by-step explanation:
5×sqrt(8)×3×sqrt(4) = 15×sqrt(8)×sqrt(4) = 15×sqrt(8)×2 =
= 30×sqrt(8) = 30×sqrt(4×2) =
= 30×2×sqrt(2) = 60×sqrt(2)
