Answer:
55°and35°
Step-by-step explanation:
let smaller angle be x
larger angle =x+20
x+x+20=90(Complementary angle)
x= 35
larger number = x+20=35+20=55°
smaller number =x=35°
Step-by-step explanation:
1st picture:
a) Red dots on -5 and 5
b) Red dots on -2 and 2
c) No solution
2nd picture:
8 and -8 because |x| gives the distance between zero to 8
The perimeter is about 82 yards
first, the perimeter of the rectangles is 30*2 = 60 (the 7 is not a part of the overall perimeter so we do not need to add it)
the "perimeter" (circumference) of the 2 semi circles = (22/7)*7 = 22by using the formula C = pi*d (2 semi circles of the same diamter = 1 circle)
now just add the 2 answers
22 + 60
= 82 yards
