What is the area of the triangle shown below
1. What is the area of the triangle shown below
a = 5
b = 5
c = 8
Keliling
= a + b + c
= 5 + 5 + 8
= 18
s = 1/2 x keliling
s = 1/2 x 18
s = 9
Luas
= √(s(s - a)(s - b)(s - c))
= √(9(9 - 5)(9 - 5)(9 - 8))
= √(9 x 4 x 4 x 1)
= √144
= 12 satuan luas
2. What is the area of the right triangle shown below
ANSWER:
60.
Penjelasanya :
(theorema phytagoras) a=[tex]\sqrt{b^{2} -c^{2} }[/tex]
a= 17[tex]\sqrt{17^{2}-8^{2} } = \sqrt{289-64}[/tex]
a=[tex]\sqrt{225} =[/tex]15
(the area of the right triangle) :
1/2 x a x h
1/2 x 8 x 15
= 60
ur welcome:)

4. 1.what are some possible lengths of each side of the triangle is isosceles?2.what are some possible lengths of each side if the triangle is scalene?tolong jawab ya kakak adik
Jawaban:
1. The triangle is formed by 3 vertices whose positions are not in line connected.
In each triangle, several properties apply, including;
the sum of the lengths of the two sides is always greater than the side lengths of the triangle;
the sum of the angles of a triangle is 180 degrees;
the largest corner is the corner facing the longest side, while the smallest corner is the corner facing the shortest side;
the size of the outer corner is equal to the sum of the two corners that are not aligned with the outer corner.
2. that the sum of the lengths of each of the two sides of the triangle must be greater than or equal to the length of the third side.

its so easy...just make a substitution and use the diskriminant properties. the K is should the vertex ordinat for y=ax2+bx+c

19. look at the right triangle below!what is the length of the side AC? berapa panjang AC?
Jawaban:
4√6
Penjelasan dengan langkah-langkah:
First,you must know the trigonometrybsics:
[tex] \sin( \alpha ) = \frac{o}{h} \\ \cos( \alpha ) = \frac{a}{h} \\ \tan( \alpha ) = \frac{o}{a} [/tex]
or simply SOH CAH TOA and the special angles (you can find the table in the internet)
Now,sinceyou know the adjacent (BD)of the lefttriangle,you can find the height (AD)using tan of Bwhich js60°
[tex] \tan(60) = \frac{ad}{4} = \sqrt{3} [/tex]
This leaves us with AD =4√3
Thenwe can substitute it into the sin of C
[tex] \sin(45) = \frac{4 \sqrt{3} }{ac} = \frac{ \sqrt{2} }{2} [/tex]
Then,you can operate this by cross multiplyingand get the final answer,which is AC =4√6
