Answer:
(3x) ° + (x+ 10)° = 90°
Step-by-step explanation:
(3x) ° + (x+ 10)° = 90°
3x + x + 10 = 90
4x = 90 - 10
4x = 80
x = 20
(3x) ° = 3 x 20 = 60°
(x + 10)° = 20 + 10 = 30°
It the multiplication property because you are multiplying 2x=20 so then you divide on both sides with 2 and that gives you 10
Answer: 28
Step-by-step explanation:
Using the similarity rule we get the equation
(10+x)/(15+42) = x/42
420 + 42x = 57x
420 = 15x
x = 420/15 = 28
658 / 4 = 164,5
