0,6(y + 3)= 4,8
6y + 18 =48
6y = 30
y = 5
Answer:
m<3 = 70 and m<4 = 110
Step-by-step explanation:
<3 and <4 are vertical angles so they add up to 180
(3y + 7) + (5y + 5) = 180
(3y + 5y) + (7 + 5) = 180
8y + 12 = 180
-12 -12
8y = 168
/8 /8
y = 21
find the angle measures:
3(21) + 7
63 + 7
70
5(21) + 5
105 + 5
110
Answer:
sum of angles = 40 + (8x + 4) + (3x + 4) = 180
Collecting all similar terms, the equation above becomes
11x + 8 = 140 ---> x = 12
Therefore. angle S = 3x + 4 = 3(12) + 4 = 40
