Answer:
Sin theta =4/5
Step-by-step explanation:
Cos theta=base/HYPOTENUSE=3/5
Hence
From here we get
Base=3,HYPOTENUSE =5
By Pythagoras theorem
Hypotenuse ²=base²+perp²
5²=3²+perpendicular²
25=9+perp²
Perp²=25-9
Perp ²=16
Perp=4(taking sq root on both sides)
Now
Sin theta=perp/hyp=4/5
Answer:
A ≈ 22.2 ft²
Step-by-step explanation:
the area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 7.13² × 
= 50.8369π ×
≈ 22.2 ft² ( to the nearest tenth )
Answer: 31 3/7
Step-by-step explanation: Simply just multiply 66 by 10 = 660 and then divide 660 by 21 and you get 31 3/7!
<u>Answer:</u> (update)
<h2>122.5 miles</h2>
<u>Explanation:</u>
given: the total length of the trip = 500 miles
hence the road's length from home to niagara falls = 500/2 = 250
Sleepy Meena missed:
250/100×49 = 2.5×49 = 122.5 miles

Answer:
2x+2y=6
Step-by-step explanation:
-4x + -2y = -18
2x + 3y = 24
2x + 2y = 6
