Answer:
x = 10
Step-by-step explanation:
to find the measure of angles we first need to find the value of x
The sum of interior angles in a triangle is equal to 180
9x + 7x + 2x = 180 add like terms
18x = 180 divide both sides by 18
x = 10 to find angle measures replace x with 10 in each representative like:
m<L = 9x and 9*10 = 90 and so on

Answer:
y = 30, x = 10
Step-by-step explanation:
y = 3x...eqn i
x = -2y + 70...eqn ii
Now,
Substituting eqn i in eqn ii,
x = -2y + 70
or, x = -2(3x) + 70
or, x = -6x + 70
or, x + 6x = 70
or, 7x = 70
so, x = 10
Now,
y = 3x = 3 * 10 = 30
