The answer would be C. Hope the picture helps.
The correct answer for the question that is being presented above is this one:
(1)
The triangle shows and equilateral triangle. Equilateral triangle has the same length of sides and angles.
60 = 1.5x
x = 40 degrees
7.1 = y + 3.4
y = 3.7 cm
(2) Isosceles Triangle
65 = 13x
x = 5 degrees
y + 2/3 = 7/8
y = 7/8 - 2/3
y = 21 - 16 / 24
y = 5/24 in
(3)
12 = x + 3.8
x = 8.2mm
Y=-5x+9
3x+2(-5x+9)=4
3x-10x+18=4
-7x=4-18
-7x=-14
x=2
5(2)+y=9
10+y=9
y=9-10
y=-1
The answer is (2,-1) :)
