Answer:
To find the perimeter of this triangle, we add up all the sides together.
(8 · √3) + (8 · √3) + √384
But before we add them, let's simplify them.
(8 · 1.7) + (8 · 1.7) + 19.6
13.6 + 13.6 + 19.6
27.2 + 19.6
= <u>46.8</u>, is the perimeter of this triangle.
Now to find the area, we use the formula:
(formula for area of a triangle)
A = BH · 1/2
Where 'B' represents the base, 'H' stands for the height, and 1/2 means that you divide the product of the base and height by 2.
<u><em>What we know:</em></u>
- Base = 8 · √3 which equals <u>13.6</u>.
- Height = 8 · √3 which equals <u>13.6</u>.
Plug in the values into our formula:-
A = BH · 1/2
A = 13.6(13.6) · 1/2
A = 184.96 · 1/2
A = 184.96/2
A = <u>92.48</u>, is the area for this triangle.
I believed you are looking for the value of e. The value of e is 16 below is the solution:
A×4 = E, so A=E/4
B/4 = E, so B=4E
C+4 = E, so C=E=4
D-4 = E, so D=E+4
and
A+B+C+D=100.
Substitute values of A, B, C and D in the equation, we get,
(E/4) + 4E + E-4 + E+4 = 100
(E/4) + 4E + 2E = 100
(E/4) + 6E = 100
(E+24E)/4 = 100
E+24E = 100×4
25E = 400
E = 400/25

Answer:
You already answered it.
Step-by-step explanation:
The 3 angles form the straight line AB. A straight line equals 180 degrees.
The 3 angles when added together need to equal 180:
2x + 65 + (x + 65) = 180
Simplify by combining like terms:
3x + 130 = 180
Subtract 130 from both sides
3x = 50
Divide both sides by 3
X = 50/3
X = 16 2/3 (16.66667 as a repeating decimal)
Now you have x if you need to solve all the angles replace x with its value and sole:
2x = 2(16 2/3) = 33 1/3
X + 65 = 16 2/3 + 65 = 81 2/3
