So, it is proven that the area of triangle ABC is [tex]\frac{1}{2} * a*b*SinC[/tex].
What is a triangle?A triangle is a 2D shape having three sides and the sum of all angles is 180°.
We have,
A ΔABC,
And,
AB = c
BC = a
CA = b
H = Altitude of the triangle,
Now,
Area of triangle [tex]=\frac{1}{2} * Base *Altitude[/tex]
i.e.
Area of triangle ABC [tex]=\frac{1}{2} * a*h[/tex] .....(i)
Now,
Using trigonometric ratios,
[tex]Sin C = \frac{Perpendicular}{Hypotenuse}[/tex]
i.e.
[tex]Sin C = \frac{h}{b}[/tex]
We get,
h = b * SinC
Now,
putting this value in equation (i),
We get,
Area of triangle ABC [tex]=\frac{1}{2} * a*b*SinC[/tex]
So,
It is proved that area of triangle ABC [tex]=\frac{1}{2} * a*b*SinC[/tex] ,
Hence, we can say that it is proven that the area of triangle ABC is [tex]\frac{1}{2} * a*b*SinC[/tex], using trigonometric ratios and the triangle's area formula.

If the walls of a square room require 480 ft^2 of paint and the floor to ceiling height is 10
ft, what are the dimensions of the room?
Answers
After find the area of one side, we proceeded to find the length and with as
Length = 10.95 feet width = 10.95 feet
Mensuration of ShapesGiven Data
Height of the Room = 10 feetArea of 4 sides of the room = 480 ft^2If the area of 4 side = 480 ft^2
Area of 1 side will be = x
Cross multiply we have
x = 480/4
x = 120 ft^2
Let us find the length and width of the room
x = √120
x = 10.95 feet
hence Length = 10.95 feet
width = 10.95 feet
Height = 10 feet

Step-by-step explanation:
b = 147° ( vertically opposite angle )
c + 147 ° = 180° ( supplementary angle )
c = 180° - 147°
c= 33°...
Answer:
Step-by-step explanation:
b = 147° {Vertically opposite angles are congruent}
Linear pair: A linear pair is a pair of adjacent angles whose non-common arms form a line ( opposite rays)
c + 147 = 180 {Linear pair}
c = 180 - 147
