Answer:
y = 9 x= -11
Step-by-step explanation:
opposite angles of a trapezoid are supplementary.
The two angles of the same base in an isosceles triangle are congruent.
-6x-16 = 50
-6x = 66
x= -11
The supplementary of 50 is 130
3x+16y+19 = 130
-33 +16y +19 = 130
16y = 144
y = 9
The sum of all 4 angles is 360 degrees
(x+10)(x+1)( x-3) ( x-3)
root of 3 with multiplicity 2
( x-3) ^2 or ( x-3) ( x-3)
root of -10
(x- -10) is (x+10)
root of -1
(x - -1) is (x+1)
( x-3) ^2 (x+10)(x+1)
The acute angles of a right triangle are complementary, so:
