Answer:
No, It is not a right triangle
Step-by-step explanation:
For it to be a right triangle, the hypotenuse would be equal to the sum of the legs when squared.
Use the pythagorean theorem-
8^2+12^2=15^2
64+144=225
208=225
Since they aren't equal, it is not a right triangle.
Answer:
Yes
Step-by-step explanation:
SI=PRT/100
SI=A-P
R=SI×100/P×T
T=SI×100/R×T
P=SI×100/R×T
Answer:
1) No
2) Yes
3) angle UXS = 120 degrees
4) arc CB = 40 degrees
Step-by-step explanation:
If AB is tangent to the circle, then angle at A would be 90 degrees.
1)
Is 13^2 + 14.6^2 = 19.4^2?
169 + 213.16 = 376.36 No
2)
Is 8^2 + 6^2 = 10^2?
64 + 36 = 100 Yes
3)
arc WS = arc VU + arc TU = 113 degrees
arc ST = arc WV because their chords cross making a pair of vertical angles.
full circle = 360 degrees
360-113 - 113 = 134 degrees
134/2 = 67 degrees for arc ST
arc STU = 67 + 53 = 120 degrees
Angle UXS = 120 degrees
4) arc CB = arc FB = 40 degrees because their chords cross making a pair of vertical angles.
Answer:
No
Step-by-step explanation:
Because 0,0 is not the starting point.
