You need the Law of Cosines here and you use it when you have 2 sides and an enclosed angle. The side across from the angle is the one we are looking for. The correct way to express the Law using what we have is the last choice above. Side RT is the unknown, and it is across from the angle that is enclosed between the 2 other sides.
Answer:
The first answer choice
Step-by-step explanation:
Formula for volume of a rectangular pyramid is V=lwh/3
To find the quotient you do 6/ (-1/2). You keep, change, flip when dealing with fractions.
Answer:
TRUE
Step-by-step explanation:
In an isosceles trapezoid, the base angles are equal and therefore the nonparallel sides are congruent.
The parallel sides are never congruent.
The scale for the model length of the fuselage obtained by taking the ratio of the model length and the actual length is 0.125
Actual Length of fuselage = 170 feets
Length of fuselage on model = 21.25
<u>To obtain the scale of the model, we take the ratio of the model length and the actual length</u> :
- Model length / Actual length
- 21.25 feets / 170 feets = 0.125
Therefore, the scale for the model length of the fuselage is 0.125
