Answer:
f=127 cm
Step-by-step explanation:
Law of Cosine:
x squared=92 squared+42 squared-2(92)(42)(cos 141)
x squared =8464+1764-7728(cos 141)
x=127 cm
Answer:
The answer is D, 47.1.
Step-by-step explanation:
Circumference is the diameter multiplied by pi, 15 * 3.14 is 47.1, so your current choice is correct.
Answer:
Step-by-step explanation:
y=3+2x
3x-2(3+2x)=5
3x-6-2x= 5
3x-2x=5+6
x=11
y=3+2x=3+2x11=3+22=25
Only E) is true. If I were to arbitrarily pick x = 2.2 and y =1.1, then I could show that A), B), C), and D) to be false, given x/y = 2.2/1.1 = 2 (which is an integer). However for E), if we define x/y = n where n is an integer, then by rearranging terms, we can show x = n*y where n still equals an integer and our original equation is still valid.
Answer:
∆VXW and ∆BDC are congruent
Step-by-step explanation:
to proof:∆VXW and∆BDC are congruent
proof:
statements reasons
1.in ∆VXW and ∆BDC, 1.
i.VW=BD(S) i.given
ii.VX=CD(S) ii.given
iii.XW=BC(S) iii.given
2.∆VXW and∆BDC 2.using S.S.S axiom
are congruent
hence proved.
