Answer:
The measure of EHG = 120°
Step-by-step explanation:
There are three vectors originating from point H and joining three points E, F and G.
The given angles between vector HG and HF is 30° and between vector HE = 90°
Therefore, Angle between vector HE and HG = angle between HE and HF + angle between HF and HG.
∠ EHG = ∠ EHF + ∠ FHG
= 90° + 30°
= 120°
The measure of EHG = 120°
Circumference = diameter x PI
Circumference = 3.14 x 68 yards = 213.52 yards.
Area = PI x r^2
r = 1/2 the diameter = 1/2 x 68 = 34 yards.
Area = 3.14 x 34^2 = 3.14 x 1156 = 3629.84 yards^2

C
1:18
D
18:1
Answer: 18:1
Step-by-step explanation:
450 students : 25 teachers
18 students : 1 teachers
450/25= 18
Answer:
D. 18 : 1
Step-by-step explanation:
Students : teachers and aides
450 : 25
Treat it like a fraction. 450 over 25 simplifies to 18 over 1 because 450/25=18 and 25/25=1.
Therefore, the ratio is 18 : 1
