Answer:
x=71
Step-by-step explanation:
Since this is an isosceles triangle the bottom 2 angles are equal.
The three angles of the triangle are x, x, and 38. They must add to 180 degrees
x+x+38 = 180
Combine like terms
2x+38=180
Subtract 38 from each side
2x+38-38 = 180-38
2x = 142
Divide each side by 2
2x/2 =142/2
x =71
3/4 x 13/1 = 39/4 or 9 3/4 or 9.75
Answer:
Missing Number) 55
Property being used) Distributive
Step-by-step explanation:
To find the missing number, just plug in reasonable numbers from the other equation. It is distributive because the 55 is being distributed into everything that is inside the parentheses. If you need more help, comment and I'll be more than glad to assist you! :P
Number one is really easy just set it up in proportions. 420 over x and 7 hours over 24 cause you know there 24 hours in a day and then cross division and simplify. I think.
