Answer:

Step-by-step explanation:
We need to find m ∠EGD.
From the given figure, we can see that, ∠BGA & ∠EGD are vertically opposite angles (opposite angles that share the same vertex ⟶ G).
Also, vertically opposite angles are equal to each other.
Given, ∠BGA = 30°
So, ∠EGD = ∠BGA = 30°.

Answer:
62.83
Step-by-step explanation:
Circumference=2 pi r
diameter=20
20*pi= about 62.83
so it sould be around 62.83
3.7kg is also equal to 3700 grams
3700+620 grams
= 4320 grams
= 4320/1000 kg
= 4.32 kg
Answer:
Step-by-step explanation:
There is theorem in this chapter which explains the answer
According to the theorem ,
/_rbd = 2 /_ rad
Therefore , rbd = 34 ° .
Hence , rad = 2x 34
Therefore , rad = 68°
