All of the positive numbers you can think of without a decimal point is greater than all of those numbers .
Let x and y represent the measure of the unknown angles
x+y=145
x-y= 15
2x=160 (Use the elimination. method)
2/2x=160/2
x=80
80° is the measure of one of the unknown angles
x+y=145
80+y=145
-80 -80
y=65
The measure of the second unknown angle is 65°
Thus the measure of the unknown angles are 80° and 65°
Answer:
x=y/m - b/m
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Step-by-step explanation:
The expression can be factored using the factors of 14, 2 and 7, which add to give 9.
x² -9x +14 = (x -2)(x -7)
One of the factors is (x -2).
