Answer:
67 degrees
Step-by-step explanation:
It is given that,
The measures of the three angles of a triangle are 43°, 70°, and xº.
We need to find the value of x.
We know that, the sum of angles of a triangle is equal to 180 degrees. Applying this theorem, we get :
Hence, the value of x is 67 degrees.
The sets that the number -14 is an element of include:
- Integers.
- Rational numbers.
- Real numbers.
<h3>What kind of number is 14?</h3>
-14 falls under various sets of numbers including integers. It is an integer because it is a whole number that does not have a decimal.
-14 is also a rational number and this is because it does not have an infinite value after the decimal point.
-14 is a real number as well. This is simply because it is a rational number. All rational and irrational numbers are real numbers so -14 is a real number.

2. 1/3 (1 third)
3. -3
4. -1\2 (negative one and a half)
5.-4
6. 1.66666
Step-by-step explanation:
1. Let's solve your equation step-by-step. ( x + 5 ) ( x − 2 ) = 0 Step 1: Simplify both sides of the equation. x 2 + 3 x − 10 = 0 Step 2: Factor left side of equation. ( x − 2 ) ( x + 5 ) = 0 Step 3: Set factors equal to 0. x − 2 = 0 or x + 5 = 0 x = 2 or x = − 5. <—— this is for the first explanation
2. Step 1: Simplify both sides of the equation. 6 x 2 + 13 x − 5 = 0 Step 2: Factor left side of equation. ( 3 x − 1 ) ( 2 x + 5 ) = 0 Step 3: Set factors equal to 0. 3 x − 1 = 0 or 2 x + 5 = 0 x = 1 3 or x = − 5 2 Answer: x = 1 3 or x = − 5 2
<———— this is for the second explanation
3.Step 1: Factor left side of equation. ( x + 1 ) ( x − 4 ) = 0 Step 2: Set factors equal to 0. x + 1 = 0 or x − 4 = 0 x = − 1 or x
<———- this is for the third explanation
4.Step 1: Factor left side of equation. ( 2 x + 1 ) ( x − 3 ) = 0 Step 2: Set factors equal to 0. 2 x + 1 = 0 or x − 3 = 0 x = − 1 2 or x = 3
<—————- this is for the fourth explanation
5. Step 1: Add 16 to both sides. x 2 − 16 + 16 = 0 + 16 x 2 = 16 Step 2: Take square root. x = ± 16 x = 4 or x = − 4
<—————- this is for the fith explanation
6. Step 1: Add 25 to both sides. 9 x 2 − 25 + 25 = 0 + 25 9 x 2 = 25 Step 2: Divide both sides by 9. 9 x 2 9 = 25 9 x 2 = 25 9 Step 3: Take square root. x = ± 25 9 x = 1.666667 , − 1.666667
<—————- this is for the sixth explanation
Hope this helps :)
Answer:
1/2.
Step-by-step explanation:
Let O = an odd number and E an even number.
The possible outcomes for an odd sum are:
OOO
OEE
EOE
EEO
The probability of an odd on each pick = 50/100 = 1/2 and for an even it is also 1/2.
Prob( O O O) = 1/2*1/2*1/2 = 1/8.
The probability for the other 3 possible outcomes is also 1/8 , therefore the probability for odd number totals = 4 * 1/8
= 1/2.
