Answer:

116 degrees

Step-by-step explanation:

The sum of all three angles of a triangle is 180 degrees.  Here we know two of these angles immediately:  65 and 51 degrees.  The third is 180 - (65 + 51), degrees, or 64 degrees.

Angle PST and this 64 degree angle form straight angles; their sum is 180 degrees.  We are to find Angle PST.  Do that by subtracting 64 from 180:

Angle PST = 180 - 64 degrees, or 116 degrees.

Answer:

116°

Step-by-step explanation:

The angles of any triangle will add up to 180°. Since we know the measures of ∠SPR and ∠PRS, we can find the measure of ∠PSR by adding the two measures and subtracting from 180°.

61+51 = 116

180 - 116 = 64

Now we know the measure of ∠PSR. Note that ∠PSR is supplementary to ∠PST, meaning that both values add up to 180. Let's do the math then.

180-64 = 116

This means that the measure of ∠PST is 116°.

Hope this helped!

Probability of success =

         (number of possibilities that would be considered successful)
divided by
         (total number of different possible outcomes) .

Total number of different possible outcomes =

       total number of different possible values of the last 2 digits

   =  the quantity of numbers from  00  to  99

   =    100 of them .

The number of possibilities that will match your age  =  only 1 .

Probability that the last 2 digits match your age = 1/100  =  0.01  =  1 % .

What is the solution to (x+6)(x+2)=60
Citrus2011 [14]
Distribute to eliminate the parenthesis

x^2 + 2x + 6x + 12 = 60

Combine like terms

x^2 + 8x + 12 = 60

Subtract 60 from both sides

x^2 + 8x - 48 = 0

Factor the equation

(x+12)(x-4)=0
x+12=0
x+4=0

x= -12 and -4
