B.o 28.89°
C.o 56.51°
D.o 33.49°
The value of x is 33.49°.
A triangle with one of its angles measuring 90° is known as a right triangle.
Given a right triangle with a hypotenuse of length 58 and a leg of length 32.
Use the sine rule:
(sin90°) / 58 = (sinx) / 32
sinx = 32/58
x = sin⁻¹ ( 32/58)
x = 33.49°
Hence, the value of x is 33.49°.

Answer:
D. 33.49
Step-by-step explanation:
2x-4xy+5x-2xy-4x-4y?
Answer: 3x-6xy-4y
Step-by-step explanation: So, it’s been a few years since I’ve been in high school, but if I remember correctly...it should break down as such...
A good method to breaking this down is to use parentheses to break up the equation.
Example: (2x)(-4xy)(+5x)(-2xy)(-4x)(-4y)
Keep in mind we are only using the parentheses as a breaker and not as multiplication as it can be seen.
So, start with the singular ‘x’ variants. (2x) (+5x) (-4x). 2x+5x is 7x. 7x-4x is 3x. Now, move onto ‘xy’ variant. (-4xy) and (-2xy). As these are both negative, they add together to make an even lower number...being -6xy. Onto the final step taking the singular ‘y’ variant. There’s only 1 ‘y’ variant so it just stays -4y.
In the end, you end up with 3x-6xy-4y. :) Hope this helps. If you have any more questions, let me know!
B) 40
C) −2
D) 14
Answer:
f(x)= 2 × (x+8)------(1)
f(x)=12---------(2)
Equating (1) and (2)
⇒2×(x+8)=12
⇒Using distributive property of multiplication with respect to Addition
⇒2 x +16=12
⇒2 x+16-16=12 -16-----[Subtracting 16 from both sides]
⇒2 x= -4
Dividing by , 2 ,on both sides
⇒x= -2
Option C: -2
the extra amount added to the cost price to arrive at the selling price
the extra amount added to the marginal cost to arrive at the selling price
Answer: Second option is correct.
Step-by-step explanation:
Markup is the extra amount added to the cost price to arrive at the selling price.
As in retail market , cost price is always marked up by the retailers to make some profit and cover overhead expenses.
So, Markup is that amount that is added to the cost price.
Discount is also given to that amount only, to increase his goodwill.
Hence, Second option is correct.
