Answer:
x=-2, y=-9/2. (-2, -9/2).
Step-by-step explanation:
x=2y+7
3x-2y=3
--------------
3(2y+7)-2y=3
6y+21-2y=3
6y-2y+21=3
4y+21=3
4y=3-21
4y=-18
y=-18/4
simplify
y=-9/2
x=2(-9/2)+7
x=-9+7
x=-2
Answer:
AB = 4/cos25
Put in calculator and put to the nearest hundredth or 2 dp
Step-by-step explanation:
The angle 25 is the starting point and adjacent is 4 and the unknown or we will call it x is the hypotenuse.
We will use CAH
Cos25 = 4/x
We need x by itself so
x = 4/cos25
Put in calculator and put to the nearest hundredth or 2 dp
