Sum of angle in a triangle is 180, so 33+70+x=180
x=77
x and y are vertical angles so y=77
Answer:
see below
Step-by-step explanation:
CD = 90 - 53 = 37°
AB = 180 - 79 - 53 = 48°
ED = 180 - 37 = 143°
EB = 180 - 53= 127°
BDE = 53 + 37 + 143 = 233°
DEC = 360 - 37 = 323°°
Total Area = 2( 32 x 79) + (26 x 42) = 6148 m²
Number of 4 m² = 6148 ÷ 4 = 1537
Answer: The zoo can have 1537 plants.
