Answer:
ASA
Step-by-step explanation:
One pair of corresponding angles (in the bottom left/right) are already marked for us, and we're also given a pair of corresponding sides (the 8cm ones on the left and right). The two triangles have one more angle in common too - the one they're overlapping on the top corner. So, we have:
- Two pairs of congruent corresponding angles, and
- A pair of congruent corresponding sides between them,
which is enough information to call the triangles congruent by Angle-Side-Angle (ASA).
Answer:
The area of each section of the circle is 
Step-by-step explanation:
we know that
Each section represent a quarter of circle
The area of a quarter of circle is equal to

Step-by-step explanation:
Answer:
x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65
Step-by-step explanation:
x= −b±√b2−4ac
/2a
x=
−(1)±√(1)2−4(−2)(8)
/2(−2)
x=
−1±√65
/−4
x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65
Answer:
15
Step-by-step explanation:
Let index 1 refer to the first point, while index 2 refers to the second one.
The distance d:
d²=(x2-x1)²+(y2-y1)²=(-5-7)³+(3-(-6))²=
(-12)²+9²=144+81=225=15²
d=15
