36% in decimal from it .36
172.80 + .36 = 173.16
So original price was 173.16
Answer:
Triangle PQR is a right triangle therefore you can use the pythagorean theorem to find the length of PR which is the same as the hypothenuse
Step-by-step explanation:
Theorem:
(QP)² + (QR)² = (PR)²
(6)² + (14)² = 232 ⇒ (PR)² = 232 then PR = √232 = 15.23
If PR is adjusted to 16 feet then we use the Pythagorean theorem again to find the height QR
(QR)² + (14)² = (16)²
(QR)² = 256 - 196 = 60 ⇒ QR = √60 = 7.75.
Answer:
x=2+i, x=2-i
Step-by-step explanation:
x^2-4x+5=0
Apply the quadratic formula.
There's a lot of theorems SAS, ASA, SSA, AAS, SSS
S=Side
A=Angle
If the order of the sides and angles in one of the above are congruent, then the triangles are congruent.
Hope this helps :D
