In ΔABC, if m ∠A = m∠C, m∠B = ß (where ß is an acute angle), and BC = x, which expression gives the length of b, the side opposi
chubhunter [2.5K]

Answer:

The length of b is \sqrt{2x^2(1-cos\beta)}.

Step by step explanation:

Given information: In ΔABC, ∠A =∠C, ∠B = ß (where ß is an acute angle), and BC = x.

Since two angles are same therefore triangle ABC is an isosceles triangle and side AB and BC are congruent.

AB=BC=x

According to Law of cosine

b^2=a^2+c^2-2ac\cos B

b^2=x^2+x^2-2(x)(x)\cos \beta

b^2=2x^2-2x^2\cos \beta

b^2=2x^2(1-\cos \beta)

\sqrt{2x^2(1-cos\beta)}

Therefore the length of b is \sqrt{2x^2(1-cos\beta)}.

What is the area of the real backyard?
prohojiy [21]
50 meters, because if 4cm is 5 m, then it would be 5( 4cm, which equals 5m) multiplied by 10( 8cm÷4cm= 2.     2×5m= 10). So 5m × 10m = 50m. Hope this helps!

Situation One
navik [9.2K]

Step-by-step explanation:

Total no. of horses and chicken=24

C+H=24

Total no. horses be =24-C

Total no. legs=66

---66=4(24-C)+2C { As horses have 4 legs and chicken has 2 legs}

66=96-4c+2c

66-96=-2c

-30=-2C

Chicken=15

Therefore no. horses=24-C

=24-15

=9horses

There fore no. of chicken legs=15×2 = 30 legs

Therefore no. of horse legs=9×4=36 legs
