Two angles of a triangle have equal measures, but the third angle's measure is 36° less than the sum of the other two. Find the
zimovet [89]
<span>Draw a triangle and label is ABC.
Let angle A = x
let angle B = x
let angle C = 2x - 36
2x - 36 means that angle C is 36 degrees less than the sum of angle A and B.
Since the sum of the interior angles of a triangle is 180 degrees, then 2x + 2x - 36 = 180.

combine like terms in that equation and you get 4x - 36 = 180
add 36 to both sides of that equation and you get 4x = 216
divide both sides of that equation by 4 and you get x = 54 degrees
angle A = 54 degrees
angle B = 54 degrees
angle C = 108 - 36 = 72 degrees
54 + 54 + 72 = 108 + 72 = 180 degrees so the angles are good because they add up to 180 degrees and the third angle is 36 degrees less than the sum of the other 2. </span>

VMariaS [17]

Answer:

Look below.

Step-by-step explanation:

Q1. Impossible goes with probability = 0

     Unlikely goes with probability < 1/2

     Likely goes with probability > 1/2

     Certain goes with probability = 1

Q2. So there are 25 aprons in all. Without green there are 18

      18 / 25

Q3. Yes, because the everyone gets a fair chance in being picked first since there are 18 kids and 18 slips.

Q4. Number 2 is true

      Number 3 is true

      Number 5 is true

     

Q5. There is a probability of 0 because there is only the number 1 - 12 on the die. No greater.

Since lines TS and GF are congruent that means that they are the same length.

Use the equation 12=2x-16 and simplify and you get:


X=14 since the side length is 12
