Please help if you understand!! I hope everyone has a great day or is having a great day

Monica [59]

Answer:

Firstly, notice the relationship the two triangles have. They have conjoining ends that form vertical angles (looks like a middle x). Vertical angles are equivalent in measure of degrees.

Secondly, notice that the triangle on the right side is a right triangle. One of its angle's measurements are also given; 40 degrees. If you know that the sum of a triangle's angles equal 180 degrees, then simply subtract the known angles measurements from 180.

180-(90+40)= 180-130=50.

Therefore, the vertical angles measurement is equivalent to 50 degrees.

Apply the principle of the sum of all angles in a triangle equivalent to 180 degrees to the left triangle, and you will be able to find the measurement of the "?" angle.

180-(50+25)= 180-75=105

SO HERE IS YOUR ANSWER= 105 degrees is the value of the angle marked with a "?"

I hope you are having a great day too;)!

Thalia has a circular pool in her backyard. The diameter of the pool is 10 ft. Explain in writing (typing) how to find the radiu

Vesna [10]

Answer:

Since the diameter of the pool is 10 feet, the radius will be one-half of the diameter.

The radius will be 5 feet.

The circumference of the pool will be Pi times the diameter.

The circumference will be Pi (3.14) times 10 feet.

The circumference will be 31.4 feet.

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> In x = 3

mixer [17]

Answer:

The solution is:

$x = e^{3} = 20.09$

Step-by-step explanation:

The first step to solve this equation is placing everything with the logarithmicto one side of the equality, and everything without the exponential to the other side. So

$\ln{x} = 3$

It already is in the desired format.

Now, we have that, since e and ln are inverse operations

$e^{\ln{a}} = a$

So, we apply the exponential to both sides of the equality

$e^{\ln{x}} = e^{3}$

$x = e^{3} = 20.09$
