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

Answer:
the right answer is rectangle
Step-by-step explanation:
Compare the pairs of sides. One pair measures 4 inches, but the other pair does not and forms 90 ° angles. This figure does not have its four congruent sides, so it is a rectangle.
Answer:
zero
Step-by-step explanation:
because when u equate both equation ,
-2x-5= -2x+7
or, -2x+2x=7+5
or, 0=12
which is invalid so it has no solution
