Answer: 14.5 cm
Step-by-step explanation:
- The mid point theorem says that if line joining the midpoints of the any two sides , then this line becomes parallel to the third side and it becomes half of the third side.
Here , if consider firstly Q and R are mid-points of XW and XY then,
QR║WY such that
Similarly, RS║XW such that
Similarly, QS║XY such that
Now, the perimeter of the triangle= 
Well the formula for the quadratic equation is y = -b <u>+</u><span> √b² - 4ac / 2a
</span>Fill in the variables with the information where a = 2, b = 2, and c = -12.
The final answer is <span>y = -2 +</span><span> </span><span><span>√2² - 4(2)(-12) / 2(2)
</span>A simplified answer would be <span>y = -2 <u>+</u> </span></span><span>√4 + 96 / 4, which further simplifies to
</span>y = -2 <u>+</u> 10 / 4
This can be simplified into two answers, either y = -3 or y = 2
The resulting triangle is a right triangle with the third side given:
First, the angle can be solved using the given rise and run of the cable. So,
tan θ = 2 / 5
θ = 15.95°
Next, the lengths b and c can be solved using the solved angle:
tan 15.95 = 1320 / b
b = 3300 ft
The hypotenuse or c can be solved by trigonometric functions or using Pythagorean theorem, using the sine function:
sin 15.95 = 1320 / c
c = 4804 ft
The answer is 3. This is because the perimeter is 30 so 5x+5x+x-3+x-3 = 30. Thus you have 12x-6=30 so x = 3
Let the number be x.
x/3 + 12 = 46
Subtract 12 from both sides and you will get:
x/3 = 34
Multiply both sides by 3:
x = 102
