Hey there! Your question’s answer would be 18%..

Ok so 9/50 would be 9% out of 50% which is also 100%. If you want to find 50% turn to 100%, multiply 50 with 2 to get 100.

So you do the same thing to 9%. 9 times 2 would be 18%.

Final Result: 9% out of 100% (whole)

Can someone help me on this

Morgarella [4.7K]

Answer:

m∠A = 91°

Step-by-step explanation:

∠A ≅ ∠B (Vertical Angle Theorem). This means that the two angles will have the same measurements.

Note that a straight line = 180° (Definition of a Straight Line).

Find the value of m∠B.

180 - 47 - 42 = m∠B

m∠B = 180 - (89)

m∠B = 91°

Remember that ∠B & ∠A are vertical angles, so they will have the same measurement.

m∠A = 91°

Answer:

We conclude that we must add 4² or 16 to complete the square.

Hence, option C i.e. 16 is the correct answer.

Step-by-step explanation:

We know that the perfect square formula is

(a + b)² = a² + b² + 2ab

Given the equation

$x^2+8x$

Let us add 4² or 16 in the equation

$x^2+8x+4^2$

$x^2+\:2\left(1\right)\left(4\right)x+4^2$

as (a + b)² = a² + b² + 2ab, so

$x^2+8x+4^2=\left(x+4\right)^2$

Therefore, we conclude that we must add 4² or 16 to complete the square.

Hence, option C i.e. 16 is the correct answer.

In triangle ABC, c is the hypotenuse, 0=25°, and b =3, Find the length of c ?

Charra [1.4K]

Answer:

$\large\boxed{c\approx3.31}$

Step-by-step explanation:

Use cosine:

$cosine=\dfrac{adjacent}{hypotenuse}$

$\cos\theta=\dfrac{b}{c}$

We have:

$\theta=25^o\to\cos25^o\approx0.9063\\\\b=3$

Substitute:

$\dfrac{3}{c}=0.9063$

$\dfrac{3}{c}=\dfrac{9063}{10000}$ cross multiply

$9063c=30000$ divide both sides by 9063

$c\approx3.31$
