Answer:
Step-by-step explanation:
truncated means when its rounded up from the lower bound and upper bounds meaning lower bound=15.4 and upper bound=15.5
Answer:
4 +2
Step-by-step explanation:
= ×
=
=6 + 6 - -
=6 + 6 - 4 -
=6 + 2 -
=6 + 2 - 2
=4 +2
for = 2 ,
=
= ()^2 ×
=2 ×

Answer:
26.0 cm
Step-by-step explanation:
Given quadrilateral ABCD with diagonal BD forming triangles ABD and BCD, and angles A=90°, C=52°, ADB=35°, and CBD=52°, you want the length of CD to 3 significant figures.
<h3>Law of Sines</h3>
The law of sines tells you the relation between sides and opposite angles is ...
a/sin(A) = b/sin(B) = c/sin(C)
This lets us write two proportions that can be solved for the measure of CD.
In triangle ABD:
BD/sin(A) = AB/sin(D)
BD = AB·sin(90°)/sin(35°) = 12 cm/sin(35°) ≈ 20.921 cm
In triangle BCD:
CD/sin(B) = BD/sin(C)
CD = BD·sin(B)/sin(C) = 20.921 cm·sin(102°)/sin(52°) ≈ 25.969 cm
The length of CD is about 26.0 cm.
