Well this triangles angles have to add up to 180
If E is a perpendicular bisector with V so V= 90 degrees
and E=45 degrees
90+45=135 degrees
180 degrees -135 degrees =A) S = 45 degrees.
B) I conclude VES is a isoceles triangle because it has two corresponding angles.
C) This is a complicated one lets work this out in the comment section...
D) Same as C
Step-by-step explanation:
(3X-20)+(3X+5)=111(( SINCE 111 IS TOTAL ANGLE
6X-15=111
6X=126
X=21
EFG=3×21-20
=63-20=43
A+b+c=69
a=b+8
b=a-8
c=a/5
a is 11 (3+8= 11 which is a)
b is 3 (11-8=3 which is b)
c is 55. <span>(11 x 5=55 which is c)</span>
Answer:
(1, - 1 ) and (5, - 3 )
Step-by-step explanation:
To determine which points are solutions of the inequality.
Substitute the x/y values into the left side of the inequality and compare with the right side.
(- 6, - 3)
- 3 + 12 = 9 > - 3 ← not a solution
(1, - 1 )
- 1 - 2 = - 3 ≤ -3 ← this is a solution
(5, - 3 )
- 3 - 10 = - 13 < - 3 ← this is a solution
(0, - 2 )
- 2 - 0 = - 2 > - 3 ← not a solution
(7, 12 )
12 - 14 = - 2 > - 3 ← not a solution
I think the answer is 11 - 6√3.
