Would it be two equilateral triangles?
I'm sorry if this doesn't help I don't really know what type of triangle that is.
Given b=21 and ∠β=60°,
a = 12.12436 = 7√3
j = 24.24871 = 14√3
∠α = 30° = 0.5236 rad = π/6
h = 10.5
area = 127.30573 = 147√3/2
perimeter = 57.37307
inradius = 4.43782
circumradius = 12.12436 = 7√3
Answer is
j = 24.24871 = 14√3
Answer:
s/8 = -8
s = - 64
Step-by-step explanation:
Solution
s/8 - 12 = -20 Add 12 to both sides
s/8 -12+ 12 = -20+ 12 Combine
s/8 = - 8 Multiply both sides by 8
8*s/8 = - 8*8
s = - 64
Answer:
A, D, E
Step-by-step explanation:
The perimeter is all of the sides added together
So, since a rectangle has 2 pairs of parallel congruent sides, or 2l and 2w, anything that would result in 2l+2w would be correct.
A, l+w+l+w=2l+2w
B, l*w cant be simplified more
C, 2*l*w would end up with 2l*w due to pemdas
D, 2(l+w)=2l+2w by distribution
E, (2*l)+(2*w)=2l+2w
