For the given figure, x = 34.640 units.
Step-by-step explanation:
Step 1:
The formulae needed to solve this question are:
The triangle containing x can be split into two right-angled triangles.
So the hypotenuse of the triangle containing the length x and the already given right angle triangle's hypotenuse is the same length.
Step 2:
First, we calculate the hypotenuse of the given triangle.
The angle of the triangle is 45°, the adjacent side's length = 10√3 units. Assume the hypotenuse's length to be a units.
units.
Step 3:
For the split triangle, we have the angle as 45°, the opposite side measuring units (only half of x is in each triangle) and the hypotenuse measuring 24.498 units.
So x measures 34.640 units.

step 1
Find the lateral area
we know that
The lateral surface of a square pyramid is equal to the area of its four lateral triangular faces
so
where
----> slant height
substitute the values
step 2
Find the cost
Answer:
One of the length of the side is 13 inches, the other length is(x=8inches)which implies that the geometry is a "rectangle not square because the length of the sides are not equal.
Step-by-step explanation:
CHECK COMPLETE QUESTION BELOW;
Maria looks at the architectural plan of a four-walled room in which the walls meet each other at right angles. The length of one wall in the plan is 13 inches. The length of the diagonal of the floor of the room in the plan is approximately 15.26 inches.
Is the room in the shape of a square? Explain how you determined your answer. Show all your work.
CHECK THE ATTACHMENT FOR FIQURE THAT GIVES THE INTERPRETATION OF THE QUESTION
Using Pythagoras rule
C² = a² + b²
Where
C= Hypotenuse side= 15.26 inches.
a= adjacent side= x
b= opposite side= 13 inches
a² = b²+ C²
= ( 15.26²- 13²)
=(232.86 - 169)= 63.87
a= √63.87= 8inches
Which means the "x" side is 8inches
One of the length of the side is 13 inches, the other length is 8inches, which implies that the geometry is a "rectangle not square because the length of the sides are not equal.
Answer:
4x^3y^2+4x^2y^2- 8xy^2
Step-by-step explanation:
Isiah determined that 5a2 is the GCF of the polynomial a^3 – 25a^2b^5 – 35b^4-<u>No,Isiah is not correct if he states that that 5a2 is the GCF of the polynomial</u>
Step-by-step explanation:
Firstly ,we divide each term by the GCF and if the term does not divide evenly, then it is not valid
so,
5a^2 divide by a^3
we see that we cannot divide 5a^2 by a^3 because firstly the power is higher and then there is no 5 number.Thus it is not the GCF
The GCF of the coefficients is 1, and there are no common variables among all three terms of the polynomial.
Also we find that 5b^4 is a factor of -25a^2b^5 and -35b^4, but not a3. Additionally, a2 is a factor of a3 and -25a^2b^5, but not -35b^4.
