A number decreased by three square is: (where x is the number)
x - 3^2
Step-by-step explanation:
X = 50+45 = 95 exterior angle
y =95 + 52 = 147 exterior angle
Z = 180 Straight angle
Answer:
Step-by-step explanation:
Exponent law:


First convert radical form to exponent form and then apply exponent law.



Z=180-107
Z=73
Y= 360-(98+89+73)
Y=100
Answer:
lines r and s
Step-by-step explanation:
we know that
<u><em>Alternate interior angles</em></u> are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.
When the lines are parallel, the alternate interior angles are equal
so
In this problem
If lines r and s are parallel
then
m∠4=m∠5 ----> by alternate interior angles
