Verizon [17]3 years ago

8 0

Answer:

160 cm

Step-by-step explanation:

a square has 4 equal sides. if one of the sides is 40 cm, then all of the other sides are 40 cm as well. to get a perimeter, you add up the lengths of all the sides. if there are 4 sides of 40 cm, you multiply 40 by 4 to get 160, finally add the unit to get 160 cm.

Plsssssss help<br>got 20 mins<br>the question is: The sin of angle DCB is

Elena L [17]

Answer:

i. <DCB = $53.13^{o}$

ii. Sin of <DCB = 0.8

Step-by-step explanation:

Let <DCB be represented by θ, so that;

Sin θ = $\frac{opposite}{hypotenuse}$

Thus from the given diagram, we have;

Sin θ = $\frac{4}{5}$

= 0.8

This implies that,

θ = $Sin^{-1}$ 0.8

= 53.1301

θ = $53.13^{o}$

Therefore, <DCB = $53.13^{o}$ .

So that,

Sin of <DCB = Sin $53.13^{o}$

= 0.8

Sin of <DCB = 0.8
