Answer:
We know that an isosceles triangle has 2 of its sides being equal
With R, being the midpoint of PS, we can say that
PR=RS
Noting that, with R as midpoint, we can conclude that RT is a straight line which divides angles TPR and TSR into 2 right angle triangles
Step-by-step explanation:
therefore angle at P is 45°. Angle at S also 45°
Therefore PT = TS
This is because T is 45 degrees as well as P which is also 45 degrees
angle in triangle PTS is 180 degrees
R is 90 degrees, P is 45 degrees and the whole of T is also 45 degrees(which has been split into 2)
Answer:

Answer:
1/8n<3
Step-by-step explanation:
The letter "n" represents the number. Less than or equal to is represented by "<" but with a line under it.
Answer:
<h2>3.14159</h2>
Step-by-step explanation:
A) Pi value using circumferences
C = circumference
d= diameter
Formula: C = Pi*d⇒Pi = C/d
Circle A)
Pi = 21.98/7 = 3.14
Circle B)
Pi = 18.84/6= 3.14
B) Using areas
A = area
r = radio = diameter/2
Formula: A = Pi*(r^2 )⇒ Pi = A/(r^2)
Circle A
Pi = 38.465/(3.5)^2= 3.14
Circle B
Pi= 28.26/(3^2)= 3.14
The exact value of arcsin ( 2 √ 2 ) is π4.
