Answer:
15 and 108
Step-by-step explanation:
3*(30-25)=3*5=15
4*(12+15)=4*27=108
Answer:
P=2s+a+6
Step-by-step explanation:
The perimeter of any polygon is the sum of its sides. The sides in feet are given as
s, s+2 and a+4
Hence perimeter is
P= s + s+2 + a+4
P=2s+a+6
We know that the angle of a straight line is 180°.
So we know that (5x-5) + (2x+10) = 180
We will then solve for x
5x - 5 + 2x + 10 = 180
7x + 5 = 180
7x = 175
x = 25 (just an explanation of how we get 25)
To get angle 1, we will then plug in x=25 into the first equation to get
5(25)-5 = 125-5 = 120°
