Answer: from 10 to 15
Step-by-step explanation: Toby didn’t run as much in those five minutes, compared to his other times.
The angles within a triangle must equal 180.
180 - (50+91) = 39
Angles on a straight line also must add up to 180.
180 - 39 = 141
So x = 141
Option A, Yes the triangles are congruent by SAS.
Do you know what the vertical angle thereom is? If not, it pretty much means that two "vertical" angles (In this case, Angle EFD and Angle HFG) are congruent.
Answer: 16
Step-by-step explanation:
law of cosines says that c^2 = a^2 + b^2 -2abcosC
so c^2 = 3^2 +15^2 - 2*2*15*cos108
c^2 = 234 - (-27.8115294937
)
c^2 = 261.811529494
c = 16.18 rounds to 16
