Answer:
55
Step-by-step explanation:
Since this is an isosceles triangle, the angles at the bases of the identical legs must be equal
<A = <C
3x+40 =x+50
Subtract x from each side
3x-x+40 = x+50-x
2x +40 = 50
Subtract 40 from each side
2x+40-40=50-40
2x = 10
Divide each side by 2
2x/2=10/2
x = 5
We want to find <A
3x+40
3(5)+40
15+40
55
0.0046431 should be the answer
Answer:
14 yards
Step-by-step explanation:
1 yard is 3 feet. All you need to do is divide the amount of feet by three to convert yards to feet.
Well you add +2 and +7 to both sides, which will cancel out on the left side but will make
4x+3x=60, or 7x=60. you're going to get a weird number, like 8.5714...
