Answer:
All of the angles are 60!
Step-by-step explanation:
the sum of all angles will be 180. the angles are conguent....180-60=120
120/2=60
Answer:
w=108
Step-by-step explanation:
Using the formula
P=2(l+w)
Solving for w
w=P
/2﹣l = 240
/2﹣12 = 108
Answer:
love youre profile it's from Saiki K
Step-by-step explanation:
We use the factoring form becuase our c is zero and it in standard quadratic form so we rather factor than complete the square or quadratic formula since that is longer to do than just factor.
Answer:
The value of a is 25
Step-by-step explanation:
When two angles are supplementary, they add up to 180 degrees
Mathematically,
(30 + 2a) + (125-a) = 180
30 + 2a + 125 - a = 180
a + 155 = 180
a = 180-155
a = 25 degrees
