Answer:36
Step-by-step explanation:
Let name the missing angle in the triangle w.
We know that x+z+w=180
We also know that z+w=3z=y.
That means that w=2z.
x=2z, so, 2z+2z+z=180
z=36
Answer:
If you draw the linear line to their similar points and set equal then solve you can see their similar.... also can someone come help me answer my question? I NEED HELP PLS ANYONE!!
Step-by-step explanation:
Answer:
C/d = 31.4/10
Step-by-step explanation:
We know the formula of the circumference, which ir:
C = pi*d
Where C is the circumference and d is the diameter of the circle. If we want to know the value of the pi number we just need to divide both sides of the equation above by d:
C/d = pi*d/d
C/d = pi
Thus, we can write pi as the ratio C:d or C/d, which means, how many times the diameter enters on the circumference. In our case is:
pi = 31.4/10 = 3.14
And 3.14 is how we usually use the pi number.
The area of the reflective material is: 284 square yards.
<h3>What is a rectangle?</h3>
A rectangle is a quadrilateral with four sides and four right-angles.
it has two lines of symmetry.
Analysis:
To find the area of the reflecting material we find the area of the following shapes: trapezium + rectangle + triangle
bigger base of trapezium = 2 + 6 + 2 = 10 yard
smaller base of trapezium = 6
length of rectangle = 18 yard
width of rectangle : 2+6+2 = 10 yard
base of triangle is = 10 yard
Area of reflective material = 1/2(6+10) + 18x10 + 1/2(10)(8) = 284 square yards
In conclusion, the area of reflective material is : 284 square yards.
