Answer: The two figures are congruent since there is a rotation that carries one figure onto the other.
Answer:
12.5
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
It is NOT a RIGHT triangle so you <u>cannot use</u> 1/2 b * h
but you can use Heron's Formula
Area = sqrt( s (s-a)(s-b)(s-c) )
s = semi- perimeter = (3+6+7)/2 = 8
Area = sqrt ( 8 ( 8-3)(8-6)(8-7) ) = sqrt ( 80) = 8.9 cm^2
Answer:
136°
Step-by-step explanation:
Vertically opposite angles are always equal.
The opposite angle to x is 136°.
Both angles are vertically opposite angles, so they are equal.
