B = 2h
Area = 121
1/2 × b × h = 121
1/2 × 2h × h = 121
h × h = 121
h^2 = 121
h = square root of 121
h = 11
The height is 11 kilometers
[15 + 1/2 ] - [ 2 + 3/4 ] - [6 + 2/3 ]......convertng these to improper fractions, we have
[31 /2 ] - [11 / 4 ] - [ 20 / 3 ] getting a common denominator (12), we have
[186 / 12] - [33 / 12 ] - [ 80 / 12 ] = 73 / 12 inches = about 6.0833 inches left
Answer:
R = 11
C ≈ 69.12
A ≈ 380.13
Step-by-step explanation:
R = d ÷ 2
C = 2πr
A = 2πr²
-7/5-(-5/6)
= -7/5+5/6
=( -42+25)/30
= - 17/30

Applying the sine ratio and the law of sines, the value of h in the diagram is: B. 3.2 yards.
<h3>What is the Sine Ratio?</h3>
Sine ratio for solving a right triangle is: sin ∅ = opp/hyp.
Let's find AT in triangle BAT using the given Law of Sines:
m∠BTA = 180 - (180 - 57) - 46 = 11°
AB = 1 yd
m∠ABT = 46°
Using the law of sines, we have:
sin(m∠ABT)/AT = sin(m∠BTA)/AB
Plug in the values
sin(46)/AT = sin(11)/1
AT = sin(46) × 1 / sin(11)
AT = 3.8 yards
Find h using the sine ratio:
∅ = 57°
Opposite = h
Hypotenuse = AT = 3.8 yards
Substitute
sin 57 = h/3.8
h = sin 57 × 3.8
h ≈ 3.2 yards.
