Answer:

-9

Step-by-step explanation:

What b represents here is the y intercept.

The first thing we will do here is to find the slope.

Mathematically;

m = (y2-y1)/(x2-x1)

Plugging the values;

m = (12-3)/(7-4) = 9/3 = 3

The equation can thus be written as;

y = 3x + b

To get b, we can use any of the points since they lie on the line

Let’s use point M

Substitute the values of x and y in the equation

3 = 3(4) + b

3 = 12 + b

b = 3-12 = -9

Using the law of cosines, what is m&lt;X<br> 61, 79, 82, 91
joja [24]
Answer: 79°


Explanation:


1) Law of cosines:


In a triangle with sides a, b, c whose opposite angles are, respectively, A, B and C, the law of cosines states:

c² = a² + b² - 2 a×b×cos (C)

2) In the triangle of the figure you have

c = 9
C = X
a = 6
b = 8
⇒ 9² = 6² + 8² - 2(6)(8) cos(X)
⇒ 81 = 36 + 64 - 96cos(X)
⇒ 96cos(X) = 36 + 64 - 81 = 19
⇒ cos(X) = 19 / 96 
⇒ X = arccos(19/26) = 78.6° ≈ 79°

What is the measure of PSQ in degrees <br> 9<br> 24<br> 45<br> 54
ss7ja [257]

Answer:

m\angle PSQ=45^o

Step-by-step explanation:

we know that

m\angle PSR=m\angle PSQ+m\angle QSR ---> by addition angle postulate

substitute the given values

99^o=(3x+18)^o+(9x-27)^o

solve for x

99^o=(12x-9)^o

12x=99+9

12x=108

x=9

<em>Find the measure of angle PSQ</em>

m\angle PSQ=(3x+18)^o

substitute the value of x

m\angle PSQ=(3(9)+18)=45^o
