D = sqrt (x2 - x1)^2 + (y2 - y1)^2
(1,-2)(10.-4)
d = sqrt (10 - 1)^2 + (-4 - (-2)^2
d = sqrt (9^2 + (-4 + 2)^2
d = sqrt (9^2 + (-2^2)
d = sqrt (81 + 4)
d = sqrt 85
d = 9.2
What’s the question here ????
Answer:
0.0130 m per min. to 4 decimal places.
Step-by-step explanation:
If 2 m^3 of water is added we have volume = 2 = π 7^2 h where h is the height:
h = 2 / (π 7^2) = 0.01299 m.
The correct question in the attached figure
we know that
applying the law of sines
g/sinG=k/sinK
g=3 units
G=30°
k=4 units
K=?
so
g/sinG=k/sinK------> g*sinK=k*sinG-----> sinK=k*sinG/g
sinK=4*sin 30°/3-----> 2/3
K=arc sin(2/3)-------> K=41.81°
case 1)for angle K=41.81°the sum of the angles (H +G+K)=180°
H=180-(G+K)------> 180-(30+41.81)--------> H=108.19°
h/sinH=g/sinG-------> h=g*sinH/sinG------> h=3*sin 108.19°/sin 30°
h=5.70 units
case 2)for angle K=180°-
41.81°---------> K=138.19°
the sum of the angles (H +G+K)=180°
H=180-(G+K)------> 180-(30+138.19)--------> H=11.81°
h/sinH=g/sinG-------> h=g*sinH/sinG------> h=3*sin 11.81°/sin 30°
h=1.2 units
therefore
the answer is the option

<h3>Solution:</h3>
<u>Given:</u>
<u>In the diagram given, we can tell that:</u>
- ∠A and ∠B are a linear pair.
- ∠B and ∠C are a linear pair.
<u>This means that:</u>
- ∠A + ∠B = 180°
- ∠B + ∠C = 180°
<u>Step-1: Find ∠B.</u>
- ∠A + ∠B = 180°
- => 50 + ∠B = 180°
- => ∠B = 180 - 50
- => ∠B = 130°
<u>Step-2: Find ∠C.</u>
- ∠A = ∠C (Vertically opposite angles
- => ∠C = 50°
