Answer:

The angles are 45°, 60° , 75°

Step-by-step explanation:

<h3>Angle sum property:</h3>

Sum of all the angles of a triangle is 180°.

Equation:

3x + 5x + 4x = 180

Combine like terms,

12x = 180

x = 180/12

$\sf \boxed{x = 15}$

3x = 3 *15 = 45°

5x = 5* 15 = 75°

4x = 4 *15 = 60°

Answer: $^{60}C_{3}$ ways.

Step-by-step explanation:

$^{n}C_{k}$ is the number of ways in which $k$ distinct objects are selected from a pile of $n$ distinct objects.

In our question,there are a total of $60$ people.

So, $n=60$ .

Given that three are selected at random.

So, $k=3$ .

So,the answer is $^{60}C_{3}$ ways.

6. The mass of one coin is 16.718 grams. The mass of a second coin is 27.22 grams. How much greater is the mass of the second co

lora16 [44]

Answer:

The mass is greater by 10.502 grams. If you subtract 27.33 from 16.718, you get 10.502. Therefore, the mass of the second coin is greater than the first coin by 10.502 grams.

Quadratic equations are equation that has degree of 3. The value of x from the quadratic equation is 3

<h3>Factorizing the quadratic equation</h3>

Quadratic equations are equation that has degree of 3. Given the following equation;

5x²-11x = 1

Equate to zero

5x²-11x - 1 = 0

Find the solution using quadratic solution

$x=\frac{11\pm\sqrt{121-4(5)(-1)}}{2(5)}\\x=\frac{11\pm\sqrt{141} }{10} \\x=\frac{11\pm11.87 }{10} \\x=\frac{22.87}{18}\\ x\approx 3$

Hence the value of x from the quadratic equation is 3

Let f(X) = X + 8 and g(X) = x^2 - 6x - 7 find f(g(2)).

Gennadij [26K]

So what you do is evaluate g(2) then plug that value in for x in f(x)

g(2)=2^2-6(2)-7
g(2)=4-12-7
g(2)=-15

now
f(-15)=-15+8
f(-15)=-7

f(g(2)=-7
