Anyone can help me with math for solving for a side in the right triangles for khan academy
Elden [556K]

Answer:

7.45

Step-by-step explanation:

We are given a right triangle with one side length known and an angle know so we can use some trigonometry.

You need to find the hypotenuse so you are going to use either sine or cosine.

Since the adjacent from the angle is given (SOH-CAH-TOA) we can use cosine so,

cos(20) = 7/h

=>h = 7/cos(20)

=> 7.44924

=> 7.45

GrogVix [38]

Answer:

The number is -4.

Step-by-step explanation:

Let the number be n.

Given:

Max adds 7 to a number.

hence it is given as n+7

Multiply's the sum by -4 the result is 3 times the same number.

Hence the equation can be written as;

-4(n+7)=3n

Now Solving the above equation to find value of n we get;

-4(n+7)=3n\\-4n-28=3n\\-4n-3n=28\\-7n=28\\n=\frac{28}{7}=-4

The value of n is -4.

Now when we add 7 to number -4 we get answer as 3.

And when the sum is multiplied by -4 we get answer -12.

Also 3 times of number is equal to 3 multiplied by -4 we get answer as -12.

Hence when the sum is multiplied by -4  it is equal to 3 times of same number.

Hence from above we can say that the number is -4.

Can a trapezoid have four obtuse angles
Pavel [41]
The four angles inside EVERY four-sided figure add up to 360 degrees, no matter what the shape of the figure is.

"Four obtuse angles" means "four angles of more than 90 degrees each".

(four times more-than-90) = more than 360

so NO 4-sided figure can have four obtuse angles inside it.
