Answer:
x = 38, y = 4
Step-by-step explanation:
Since AB = BC then the triangle is isosceles and the base angles are congruent, that is
∠ DAB = ∠ DCB = 52°
Subtract the sum of the base angle from 180° for ∠ ABC
∠ ABC = 180° - (52 + 52)° = 180° - 104° = 76°
Note that ∠ ABD = ∠ CBD, thus
x = 76 ÷ 2 = 38
BD bisects the side AC, thus DC = AD = 4
Thus y = 4
Answer:
H=2
Step-by-step explanation:
S = 4LW + 2WH; S = 96, L=5, W = 4
S=2W(2L+H)=2×4(2×5+H)
96=8(10+H)
12=10+H
H=2
Answer: b:degrees
Step-by-step explanation:
When measuring an angle you always measure them in degrees.
there are 4 bases
4(90) = 360 ft
360 ft * 1yd/3 ft = 360/3 yds = 120 yds
It is 120 yds around the bases
