Answer:
It is 92
Step-by-step explanation:
12+[20(5-1)] =
12+[20(4)] =
12+[80] =
92
The value of x is 14 because the sum of all angles in kite is 360 degree option first 14 is correct.
<h3>What is linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The question is incomplete.
The question is in the picture please refer to the attached picture.
We know the sum of all angles in a kite is 360 degree
110 + (5x) + 110 + 70 = 360
290 + 5x = 360
5x = 70
x = 14
Thus, the value of x is 14 because the sum of all angles in kite is 360 degree option first 14 is correct.

3π/4 angle is in the second quadrant, so cos (3π/4) is going to be negative.
Reference angle of 3π/4 is (π - 3π/4) = π/4
cos(π/4) = √2/2
cos (3π/4) = - √2/2
Answer is C.
Answer: 15
Step-by-step explanation:
Average is sum of scores/ number of scores, from the question, average is given as 15.
Let the missing score be x
Equation for the questionis represented as: 12 + 18 + x /3 = 15
30 + x /3 = 15
Cross multiply
30 + x = 15×3
30 + x = 45
Subtract 30 from both sides
30 + x -30 = 45 -30
x = 15.
Check:
12 + 18 + 15/3 = 15
45/3 = 15
