Find the value of the variable.
Answers
When you add all of these angles, the sum should be 180°. This helps us to figure out the value of the variable.
Now, you must create an equation.
3z+14+z+90=180
4z+14+90=180
4z+104=180
4z+104-104=180-104
4z=76
z=19
∴The value of the variable is 19.
To check:
3(19)+14+19+90
57+14+19+90
90+90
180
All of the angles together have a sum of 180 degrees, meaning that our value for the variable is indeed correct.
Hope this helps.
Answer:
z = 19
Step-by-step explanation:
These are complementary angles; both angles add up to 90°.
To solve this, we can combine like terms.
3z + (1)z + 14 = 90
3z + (1)z = 4z
**3z and z are the only pair of like terms.**
After combining like terms, we can proceed to solve this problem.
4z + 14 = 90.
Since there is an addition sign in front of 14, we do the opposite, subtraction.
First, subtract 14 from 90 and 14.
4z + 14 = 90
- 14 - 14
------------------
4z = 76
**ELIMINATE 14.**
Lastly, divide 76 from 4; this is because 4 is the coefficient.
4x = 76
76 ÷ 4 = 19
Therefore, z = 19.

Answer:
shown below
Step-by-step explanation:
1. The pair of angles shown in your diagram are vertical angles. Vertical angles are each of the pairs of opposite angles made by two intersecting lines. The pairs of vertical angles have the exact same measurement. Therefore, 5x and 100 must have the same degree measurement, or 100 degrees. Thus, 5x must equal 100, so 5x = 100, and x would be 20 degrees.
2. The diagram shows a right angle (90 degrees) formed by 3x degrees and 39 degrees. 3x and 39 are complementary, which means they add up to 90, not 180 (that's supplementary). Thus, 3x + 39 = 90, 3x = 51, and x = 17 degrees.
3. The diagram shows a 180-degree angle formed by 6x degrees and 2x + 8 degrees. This means that 6x + (2x+8) equals 180. 6x + 2x + 8 = 180 and 8x + 8 = 180, 8x = 172, and x = 21.5 degrees.
4. A angle's supplement is basically 180 - (angle measure), because you are finding the angle that when formed with the original angle creates a 180 degree angle. Thus, the supplement angle would be 180 - 47 which is 133 degrees.
5. The angles 115 and (5x-10) create a 180 degree angle, which means that 115 + (5x-10) = 180. Thus, x = 15.
Answer:
5. The angles 115 and (5x-10) create a 180 degree angle, which means that 115 + (5x-10) = 180. Thus, x = 15.

if a coin is flipped and a fair die is rolled 96 times, predict how many times you would flip a head and roll a 6
Answers
Answer:
Step-by-step explanation:
on flipping a coin, we either get a heads or a tails and both the events are equally likely. So the probablity of getting a tails is 1/2.
Now
On rolling a die, we can get 6 possible outcomes(1,2,3,4,5,6)
But the favourable outcomes (an even number) are only 3. So the probablity of getting an even number is 3/6=1/2
In case. we have 2 events that need to occur together, we simply need to multiply their individual probablities to get the probablity of getting both the events together
So our required answer is
p(even number)× p(tails)= 1/2 × 1/2 = 1/4
