Answer:
There is a sub-field of geometry called formal geometry which is related to algebraic geometry and deals with topics such as formal schemes , topological rings , the comparison theorem in algebraic geometry , the Grothendieck existence theorem.
Informal geometry have the topics of definitions, measurements, and constructions of geometric shapes and figures. No attention to formal proofs is given. Subtopics include points, lines, angles, triangles, quadrilaterals, circles, area, and perimeter.
Step-by-step explanation:
Interest earned
7,500×0.055
=412.5
Deduct tax
412.5−412.5×0.2
=330
Add the remaining interest
330+7,500
=7,830
Calculate interest earned in the second year
7,830×0.055
=430.65
Deduct tax
430.65−430.65×0.2
=344.52
Add the remaining interest
344.52+7,830
=8,174.52. ...answer
The area of Triangle ACE from the given diagram is; 150 sq.units
<h3>What is the area of the triangle?</h3>
We are given;
AB = 44
AC = 30
ME = 10
Now, to find the area of triangle ACE, we need to know the length KE where K is the midpoint of AC.
Now, since AD bisects angle BAC. This means that ∠KEA = ∠MEA.
By ASA Congruence Postulate, we can say that; ΔAEK ≅ AEM
Thus, we can say that KE = ME = 10
Formula for area of triangle is;
A = ¹/₂ * base * height
where;
base = AC = 30
Height = KE = 10
Thus;
A = ¹/₂ * 30 * 10
A = 150
