Answer:
first one is C
the second it is A
Step-by-step explanation:
the equation of a circle=(x-h)^2 + (y-k)^2 = r^2
h and k are the coordinate of the origin of a circle
to find the origin which is the midpoint of the diameter which has end points
(9,1) and (1,9)
h=9+1/2 = 10/2=5
k=9+1/2 = 10/2=5
(x-5)²+(x+5)²=r²
find r which is the half distance of the diameter
d of diameter : √(x2-x1)²+(y1-y2)²
d=√(9-1)²+(1-9)²
d=√8²+8²=8√2
radius=8√2/2=4√2
(x-5)²+(x+5)²=r²
(x-5)²+(x+5)²=(4√2)²
(x-5)²+(x+5)²=32
TR>TS the sides RS and TS are congruent opposite angles are equal.
Answer:
PSQ is 61 degrees
Step-by-step explanation:
We've got small and big triangle, so, you start with the big one, to find angle PQR:
65 +43 = 108
180 - 108 = 72
(angles in triangle adds to 180)
PQR is 72
3:1
(3+1=4)
72/4 =18
SQR is 18
PQS is 54
(18x3=54)
Small triangle next:
65+54=119
180-119=61
(angles in triangle adds to 180)
PSQ is 61
Check:
180-61 =119
(angles on straight lines)
So, 180 - (43+119) should give us 18 degrees & it does.
(angles in triangle adds to 180)
Hope this helps!
