That is a isosceles triangle, therefore x and the top angle are the same.
There’s 180 degrees in a triangle.
Therefore:
(180 - 38)/2 = x
142/2 = x
71 = x
Answer:
Randall: 44, Amy: 35
Step-by-step explanation:
Four years ago, their age added up to 71. Since four years have passed and they've each grown four years older since then, their ages added up together is 79. Here is the equation for Amy: x + (x + 9) = 79. We can simplify to get 35. Now we add 9 to 35 to get Randall's age. So, Amy's age is 35 and Randall's age is 44, and 35 + 44 = 79.
<u>By substitution method </u>
5x - 3y =1
3x + 2y = 1

Answer:
x=60
Step-by-step explanation:
So basically the sum of interior angle of a triangle is 180.
Add all the values and make it equal to 180.
x+3/2x+1/2x=180
Then find x
3x=180
x=180/3
x=60 degrees
