Answer:x = 4 1/2
19-2 1/2 x2 = 14-2 1/2 x2 = 9/2 = 4 1/2
(a)
A right angle sums to 90
6x + 4x + 10 = 90
10 x = 80
x = 8
(b) straight line = 180
5x + 13 + 3x + 7 = 180
x = 20
(c) Sum of triangle angles = 180
3x + 5 + 2x + 18 + 2x + 17 = 180
x = 20
(d) Sum of two angles in right angle = 90
90 = x + 30
x = 60
Answer:
46 degrees
Step-by-step explanation:
x equals 23 so just multiply by 2
What i think the answer is 6.66 because u multiply 1/3 by 20
