Step-by-step explanation:
answer is B which is 8•5 yds and 8•5√3 yds
Answer:
A -3
Step-by-step explanation:
-2 x -3 = 6
6 x -3 = -18
-18x -3 = 54
A. Two properties are involved. 1) the additive inverse property of addition that says -1 +1 = 0, and 2) the substitution property of equality that says -1+1 can be substituted for 0.
b. The distributive property.
c. The identity property of multiplication.
d. Here, there are three properties involved. 1) the addition property of equality tha says I can add -3 to both sides of the equation; 2) the additive inverse property that says -3+3 = 0; and 3) the identity property of addition that says ( )+0 = ( ).
Answer:
cot theta = -√3
Step-by-step explanation:
we are given that cos theta = - √3/2 within the range 180° < theta < 270° and
since cos theta = adj/hyp
adj = - √3
hyp = 2
Get the opposite using the pythagoras theorem
hyp^2 = opp^2 + adj^2
2² = opp² + (-√3)²
4 = opp² + 3
opp² = 4-3
opp² = 1
opp = 1
tan theta = opp/adj
tan theta = - 1/√3
Recall that cot theta = 1/tan theta
cot theta = 1/(-1/√3)
cot theta = -√3
