<span>12X + 19Y - 3 is the answer to your question that you have asked.</span>
Answer:
x = 5, y = 3
Step-by-step explanation:
<u>Elimination method: (I will be eliminating 4y) </u>
3x + 4y = 27 --- Equation 1
x + 4y = 17 --- Equation 2
Equation 1-2: 3x + 4y - x - 4y = 27 - 17
2x = 10
x = 10 ÷ 2
x = 5
Substitute x = 5 into Equation 2:
x + 4y = 17
4y + 5 = 17
4y = 17 - 5
= 12
y = 12 ÷ 4
y = 3
Answer:
56
Step-by-step explanation:
56 & b are vertical angles so they are the same
https://slideplayer.com/amp/15944128/
The angle in the triangle = 60 degrees
so tan 60 = h / (1/2) s = 2h /s
sqrt3 = 2h / s
h = sqrt3 s / 2
B is the correct choice
