Answer:
1. 14
2.-16
Step-by-step explanation:
C) They satisfy equation A but not equation B
________________
EXPLANATION
4y - 3x = 16
4(0.25) - 3(-5) = 16
1 -3(-5) = 16
1 + 15 = 16
16 = 16
-x - 8y = 3
-5 - 8(0.25) = 3
-5 - 2 = 3
-7 = 3
Doesnt solve equation B
(Please mark me brainliest it would be much appreciated)
Answer:
Cos A = 3/5
Step-by-step explanation:
Points to remember
<u>Trigonometric ratios
</u>
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = Opposite side/Adjacent side
From the figure we can see a right angled triangle, ABC
AC = 9, CB = 12 and AB = 15
<u>To find the value of Cos A</u>
Cos A = Adjacent side/Hypotenuse
= AC/AB
= 9/15 = 3/5
Therefore the value of Cos A = 3/5
