Answer: 43 degrees
Explanation: All of the angles inside of a triangle add to equal 180 degrees. All you have to do is subtract the two angle measures from 180 degrees to get the answer.
180-90-47=43 degrees
5 % of the students choose other. 95% choose either Saturday or Sunday.
Let x be the number of students who participated.
(5/100) * x = 8 Multiply both sides by 100
5 * x = 8*100
5*x = 800 Divide by 5
x = 800/5
x = 160 students participated in the survey <<<<< Answer
Answer:
In the given options, 4+5 = 5+4 shows the best commutative property.
Step-by-step explanation:
One of the properties that can be applied on numbers is commutative property. Commutative property states that the order of the numbers on which any operation is being performed, can be swapped and the answer won't change.
Commutative property can be applied on addition, subtraction and multiplication.
<u>Commutative property of Addition:</u>
Commutative property of addition states that changing the order of adding two numbers does not change the result i.e. a+b = b+a
In the given options, 4+5 = 5+4 shows the best commutative property.
Answer:
B. 45
Step-by-step explanation:
To solve for angle A, we need to find the value of x. First, we need to find the interior angles of the triangle. We already know 2 of them, x+57 and 63+x but we need the third one. We can do that by subtracting 96 from 180 which is 84.
So now that we have the three interior angles of the triangle, we can make an equation. We already know that the sum of interior angles of a triangle is 180.
84+(x+57)+(63+x) = 180
Simplifying, we get:
204+2x=180
2x = -24
x=-12
Plugging x = -12 into x+57 gives 45 degrees. So, the answer is B.
