the diagram shows an isosceles triangle. all measurements are in cm.
3x-5 19-x
2x
work out the perimeter of the triangle
Answer: 38
Solution: An isosceles triangle has two equal sides: 3x - 5 and 19-x.; 3x - 5 = 19 - x; 4x = 24; x = 6
Let's check it out: 3(6) - 5 = 13; 19 - (6) = 13; 2(6) = 12
Two equal sides are 13 and base 12
Perimeter is 13 + 13 + 12 = 38 units
Answer is: 38
The perimeter of the given isosceles triangle is 38 cm.
What is the perimeter of an isosceles triangle?The perimeter of an isosceles triangle refers to the addition of all the three sides of the triangle. Since the base angles of an isosceles triangle have two angles and two sides equal;
We can say that the perimeter of an isosceles triangle is:
P = 2a + b
where;
a = sides of the base anglesb = third side3x - 5 = 19 - x
3x + x = 19 + 5
4x = 24
x = 24/4
x = 6
The perimeter of the isosceles triangle is:
= 3x - 5 + 19 - x + 2x
= 3(6) - 5 + 19 - 6 + 2(6)
= 18 + 8 + 12
= 38 cm

There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what sea is in simplest radical form
Answer:
C = 18
Step-by-step explanation:
There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what is C is in simplest radical form
Solution:
A triangle is a shape with three sides and three angles. Types of triangle are right angled, isosceles, scalene, obtuse, acute.
The length of the side in a triangle is directly proportional to the opposite angle (angle facing the side).
A right angled triangle is a triangle with one angle equals to 90 degrees.
Since the shortest line is 9, the angle facing the shortest line is the smallest angle. The longest line is the hypotenuse which is given as C. Trigonometric identities shows the relationship between the sides of a triangle and its angles, hence:
sin30 = 9 / C
0.5 = 9 / C
C = 9/0.5
C = 18

jack split 25 jelly beans between his brother and himself of that his brother has won more than twice the number jack has how many jellybeans does each have
Answer:
jack has 8 jellybeans and his brother has 17
Step-by-step explanation:
Jack have 8 jellies and his brother have 17 jellies.
What is fraction?A number expressed as a quotient, in which a numerator is divided by a denominator.
Total number of jellies= 25.
The jellies is to be divide between jack and his brother.
let us consider jack has 'x' jellies
Then, his brother have '2x+1'
So, x+ 2x+1=25
3x+1=25
3x=24
x=8
So, jack have 8 jellies and his brother have 2*8+1= 17 jellies.

The height of the triangle is found by solving triangle AMV for the distance MV. That is found from the trig relation ...
Tan = Opposite/Adjacent
tan(68°) = MV/AM
The length of AM is half the diagonal of the square base, so is (10√2)/2 = 5√2. The length of MV is ...
MV = AM·tan(68°) = 5√2·tan(68°) ≈ 17.50
So, the volume of the pyramid is ...
V = (1/3)Bh
V = (1/3)(100 cm²)(17.50 cm) ≈ 583.4 cm³ . . . . volume of the pyramid

Answer:
x ≈ -17.457 or 11.457
Step-by-step explanation:
The distance formula can help.
d = √((x2 -x1)² +(y2 -y1)²)
Substituting given values, we have ...
15 = √((x -(-3))² +(9 -5)²)
225 = (x +3)² +16 . . . . . . . . square both sides
209 = (x +3)² . . . . . . . . . . . subtract 16
±√209 = x +3 . . . . . . . . . take the square root
-3 ± √209 = x . . . . . . . . subtract 3
x ≈ -17.457 or 11.457
