45 degrees has two equal angles

Answer:

Option B is correct.

Step-by-step explanation:

Given ∠C is a right angle in Δ ABC

          sin A = sin B

To find: m∠A

Figure is attached.

Consider,

sin A = sin B

\frac{CB}{AB}=\frac{CA}{AB}        (using trigonometric ratio)

⇒ CB = CA

Δ ABC is isosceles right angled triangle,

using result, angles opposite to equal sides are equal in ΔABC.

we get,

∠A = ∠B

Now using angle sum property of triangle,

∠A + ∠B + ∠C = 180°

2∠A + 90 = 180

2∠A = 90

∠A = 45°

Therefore, Option B is correct.

A plant cell has length 6.6 times 10 Superscript negative 6 m and width 2.2 times 10 Superscript negative 6 m. What is the ratio
Vinvika [58]

The length/width ratio is 3/1 .

<em>l</em> = 6.6 × 10⁻⁶ m; <em>w</em> = 2.2 × 10⁻⁶ m

<em>l</em>/<em>w</em> = 6.6 × 10⁻⁶ m/2.2 × 10⁻⁶ m = 3/1
