Answer:
see explanation
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent.
Thus ∠D = ∠A and substituting values
2x = x + 31 ( subtract x from both sides )
x = 31
Hence
∠A = x + 31 = 31 + 31 = 62
∠D = 2x = 2 × 31 = 62
Answer:
3
Step-by-step explanation:
x-y^2
Let x = 12 y=3
12 - (3)^2
12 -9

Answer:
Each magazine costs 3.90
Step-by-step explanation:
Take the total cost and divide by the number of magazines
46.80/12
3.90
Since triangle is isosceles, that means that unknown angles are equal. 180-72=108
108:2=54
So you’re answer would be: 54 degrees.
