Answer:
50
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
A + B + C = 180
2x-10 + 70+ x+30 = 180
Combine like terms
3x +90 = 180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide by 3
3x/3= 90/3
x=30
We want to find angle A
A = 2x-10
=2*30 -10
=60-10

<h3>80ft squared </h3><h3 /><h3 /><h3 />
Subtract 2.1 from both sides:

Add 1.4y to both sides:

Of course, we can rewrite this as

Divide both sides by 1.4
