Answer:
The hypotenuse is 
times as long as either leg
Step-by-step explanation:
a true statement about a 45-45-90 triangle
The common ratio of 45-45-90 degree triangle is
x:x:
Suppose the value of x is 1 then the ratio becomes
1:1:
1 is the side length of the triangle and is the hypotenuse
The hypotenuse is times as long as either leg
8pi

Answer:
(1, - 3 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ), thus
T(- 3, - 1 ) → T'(1, - 3 )
Answer:
arc AC = 111°
Step-by-step explanation:
∠APC is a central angle, so arc AC is equal to the measure of ∠APC.
∠APC and ∠BPC are supplementary. So, m∠APC + m∠BPC = 180
m∠APC + 69 = 180
m∠APC = 111
arc AC = 111°
