Answer:
24.14
Step-by-step explanation:
more than means to add. So,
23.14 + 1 = 24.14
Answer:
Step-by-step explanation:
As the the length of the segments BC = AC, so the triangle ABC must be an isosceles triangle.
As CD ⊥ AB, it means the base AB gets bisected by CD, making two congruent angles named as ∠ACD and ∠BCD. As shown in attached figure.
CD bisecting the base AB into two equal parts means if AB = 4, then
the length of AD = 2 and the length of DB = 2. Hence, AD = DB
As BC = AC, it means these two equal sides of isosceles triangle would make equal angles on the opposite side. Hence, angle ∠A and ∠B would be equal as shown in attached figure.
As CD is bisecting the base AB into two equal parts. Hence, it can be treated as the part of two right triangles named ACD and BCD.
So, the length of AC can be easily determined using using the Pythagoras formula.
So,
c² = a² + b²
Hence

Answer:
8
Step-by-step explanation:
x = centesimal angle (100 degrees in a right angle)
y = sexagesimal angle (90 degrees in a right angle)
x - y = 15
x×90/100 = y
x×9/10 = y
x - x×9/10 = 15
10x/10 - 9x/10 = 15
x/10 = 15
x = 150
y = 150×9/10 = 15×9 = 135
using centesimal system :
the sum of all external angles in a polygon is 400 degrees (a full circle).
one external angle is the complement of one internal angle to 200 degrees = 200-150=50 degrees.
to find the number of sides of the polygon we need to find the number of angles or corners. and that is how many external angles fit into the full circle.
n = 400/50 = 8
the polygon has 8 sides
