Let us look at the image attached:
We can see that the height of the cone is 25.3 units and the diameter of the base is 10.4 units.
Now, the diameter of the base is 10.4 units so the radius of the base is given by
From the figure attached we can see that the height of the perpendicular in the triangle is 25.3 units and the length of the base is 5.2 units.
So, the angle made by the side of the cone with the base is given by
Therefore, the side of the cone makes with the base of the cone.
Answer:
Step-by-step explanation:
Two ∆s can be considered to be congruent to each other using the Side-Angle-Side Congruence Theorem, if an included angle, and two sides of a ∆ are congruent to an included angle and two corresponding sides of another ∆.
∆ABC and ∆DEF has been drawn as shown in the attachment below.
We are given that and also .
In order to prove that ∆ABC ∆DEF using the Side-Angle-Side Congruence Theorem, an included angle which lies between two known side must be made know in each given ∆s, which must be congruent accordingly to each other.
The included angle has been shown in the ∆s drawn in the diagram attached below.
Therefore, the additional information that would be need is:
Answer:
-6x^2-288
Step-by-step explanation:
18x - 432 - 18x - 6x² +144
Combine like terms
-6x^2+18x-18x-432+144
-6x^2-288
Your answer is C. Hope this help :D
