This is a right triangle
so
Cos x = 109 / 134 then x = cos⁻¹ (109/134) = 35.567°
sin y = 109 / 134 then y = sin⁻¹ (109/134) = 54.433°
and
the third side = √(134² - 109²) = 77.94
Answer:
Firstly Substitute y=2x-5 into 5x-4y=-10
This will be 5x-4(2x-5)=10 now solve for x
5x-8x+20=-10
-3x=-30
X=10
Now sub x as 10 into the second equation y=2x-5
Y=2(10)-5
Y=15
The total is $29.99. Tip is $5.98. Tax is $1.87. Total is $ 37.84.
Answer:
3y + 3z
Step-by-step explanation:
(y + z)3
As the parenthesis contains 2 different variables, we cannot add them
Distribute (Multiply 3 by y and z)
3y + 3z
This is the simplest that this expression can get
Hope this helps :)
