Answer:
y = 5
Step-by-step explanation:
The 3 interior angles of a triangle sum to 180°
Sum the 3 given angles and equate to 180
100 + 4y + 25 + 3y + 20 = 180 ← simplify left side
7y + 145 = 180 ( subtract 145 from both sides )
7y = 35 ( divide both sides by 7 )
y = 5
5 x 10³
did you have same questions???
or did you put wrong number?
There are 3 rows of pictures on the wall because 2 times 3 is 6
I think is the answer because the right side =0 and so basically your left with the left side. 6(x² - 1)
