Mathematics
1 answer:

3 0

Answer:

x = 25

Step-by-step explanation:

Since these 2 angles are vertical angles, then they are both equal. Set up an equation and then solve it.

75 = 4x - 25

75 + 25 = 4x

100 = 4x

100/4 = 4x/4

25 = x

Hope this helps. Brainly will be highly appreciated.

What is the domain of f(x) = 1/x​
SCORPION-xisa [38]

Answer:

The denominator is all real numbers except 0.

Step-by-step explanation:

In the function f(x) = 1/x, x appears in the denominator. A denominator cannot be zero since division by zero is undefined.

To find what values of x must be excluded from the domain, set the denominator equal to zero, and solve for x.

x = 0

The denominator is all real numbers except 0.

im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to t
deff fn [24]

Answer:

Step-by-step explanation: How do you find the 3rd angle of a triangle?

Image result for im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to the sum of the first two angles, find the measure of each angle.

The three angles of any triangle add up to 180 degrees. Since you know two angles (35 and 40), add them together, then subtract the total from 180 to determine the degree of the third angle.

M is a directly proportional to r cubed when r=4 M=160
Paraphin [41]

Answer:

1) When r = 2, M = 20.

2) When M  = 540, r = 6.

Step-by-step explanation:

M is a directly proportional to r cubed

This means that the equation for M has the following format:

M = ar^3

In which a is a multiplier.

When r=4 M=160.

We use this to find a. So

M = ar^3

160 = a(4^3)

64a = 160

a = \frac{160}{64}

a = 2.5

So

M = 2.5r^3

1) work out the value of M when r=2

M = 2.5*2^3 = 2.5*8 = 20

When r = 2, M = 20.

2) work out the value of r when M=540

M = 2.5r^3

540 = 2.5r^3

r^3 = \frac{540}{2.5}

r^3 = 216

r = \sqrt[3]{216}

r = 6

When M  = 540, r = 6.
