Length (L): 2w
width (w): w
Perimeter (P) = 2L + 2w
78 = 2(2w) + 2(w)
78 = 4w + 2w
78 = 6w
13 = w
Length (L): 2w = 2(13) = 26
Answer: width = 13 meters, length = 26 meters
2(40)+20 = 100m
40+20= 60m
100x60= 6000m
Answer:
C. 52°
Step-by-step explanation:
In ∆CAB, m<A = right angle = 90°
m<B = 38°
m<C + m<A + m<B = 180° (sum of ∆)
m<C + 90° + 38° = 180° (substitution)
m<C + 128 = 180
m<C = 180 - 128 (subtraction property of equality)
m<C = 52°
