Answer:
66°
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
x + y = z
5n − 19 + n + 7 = 144 − 6n
6n − 12 = 144 − 6n
12n = 156
n = 13
m∠z = (144−6n)°
m∠z = (144−6×13)°
m∠z = 66°
Answer:
<em><u>d = 8</u></em>
Step-by-step explanation:
2(d -6) - 3 = 1
+3 +3
2(d-6) = 4
/2 /2
(d-6) = 2
+6 +6
(d) = 8
<u><em>d = 8</em></u>
