lyudmila [28]

Answer:

Raspuns corect: b)

Step-by-step explanation:

a4b=24, a×4×b=24⇒a×b=6

perechile de numere cu produsul 6 sunt: {1,6}  si {2,3}

a4b in baza 10=100a+40+b

100×1+40+6=146

100×6+40+1=641

100 ×2+40+3=243

100×3+40+2=342

146+641+243+342=1372

Raspuns corect: b)

In ΔEFG, the measure of ∠G=90°, the measure of ∠E=20°, and GE = 75 feet. Find the length of EF to the nearest tenth of a foot.
LenKa [72]

Answer:80 feet

Step-by-step explanation:

Sum of < in a triangle is 180°

<G + <E + <F=180°

90 + 20 + < F = 110

< F = 70°

Using sine rule

sin G\EF = sin F\EG

sin90°\EF = sin70°\75

EF = 75sin90°\sin70°

= 79.81

=80 to the nearest tenth feet.

Find b. Round to the nearest tenth.
Svetradugi [14.3K]
Find Angle B:  B = 180 - (82+55) = 43.  Then apply the law of sines:

   b            8 cm
--------- = ----------
sin 43       sin 55
                                        (sin 43)(8 cm)
Solving for b, we get b = ------------------- = 6.66, or 6.7 (cm, to the nearest tenth).
