Answer:
A: 38º
Step-by-step explanation:
Triangle JKL is an isosceles triangle as JK=KL:
- That means ∠J=∠L=71º
- The sum of a triangle's interior angles is 180º, so ∠K=180º-∠J-∠L. We know ∠J=∠L=71º, so ∠K=180º-71º-71º=38
Answer:
Center = (0, -10)
Radius = 4 units
Step-by-step explanation:
Fv=500×(1+0.04×3)+250×(1+0.04×2)+
250×(1+0.04×1)=560+270+260=1,090
Answer:
Step-by-step explanation:
the order is 6
The answer is show that the slope of line SQ is 1 and the slope of line PR is -1.
Suppose a square has the following coordinates (0,0), (a, 0), (0, a), and (a,a).
The diagonals are distinct by (0,0) to (a,a) and (a,0) to (0,a)
The slope from (0,0) to (a,a) = (a - 0)/(a - 0) = a/a = 1 The slope from (a,0) to (0,a) = (0 - a)/(a - 0) = -a/a = -1
Two lines are thought to be perpendicular when their slopes are negative reverses of each other. In math, m2 = -1/m1
1 = -1/-1, thus these two lines, the diagonals of the square, are perpendicular.
