Answer: 57
Step-by-step explanation:
The sum of the two inside angles(y + y) , not neighbouring to the outside angle(114), equals to the outside angle) (114
Then
2 y = 114
Y = 57
A rectangle is a figure with 4 straight lines, and 4 right angles. preferably with unequal adjacent sides.
Answer: 3x + 2y - 4z= -7= <em><u>-5/8</u></em>
<em><u></u></em>
x - 4y + 3z = 10= 11
2x + 2y - 3z= -5= -2
Step-by-step explanation:
F(-3) = -2(-3) + 3
f(-3) = 6 + 3
f(-3) = 9

Answer:
Step-by-step explanation:
If congruent the sides are equal
15x-9=7x+11
8x=20
x=20/8=2.5
