Answer:
Its 48 °
Since its a triangle, the total angle will be 180°
So,
x° + 42°+90°=180°(90° as one angle in triangle is 90°)
x°=180°-90°-42°
x°=48°
Answer: 48º c:
Step-by-step explanation: So basically the angle at the top, lets call it A, is 42º. And the angle at the bottom right, is a right angle, which is 90º. We know this by the square at the angle. If we call this angle B, then through the fact that triangles will always have a combined angle measuremnt of 180º, we can do a + b + x = 180, which will be 42 + 90 = 132, 180 - 132 = 48 :)

Victor wants to see if positively greeting children as they enter the classroom reduces problem behaviors. He randomly assigns 10 second- and third-grade classrooms to one of two conditions: classes where the teacher greets each student by name and with a smile as they enter the classroom and classes where the teacher does not greet students. During a 4-week period, he asks teachers to track the number of problem behaviors per classroom on a daily basis via a strict protocol he has designed. What is the control group
The control group in the experiment are the classes where the teacher does not greet the students
A control group in an experiment is made up of groups of people that do not receive the experimental treatment.
The purpose of a control group is to allow the researcher study one variable at a time.
Victor is conducting an experiment on if positively greeting children as they enter the classroom reduces problem behaviours.
The experimental treatment here is positively greeting the students.
The group that do not receive this experimental treatment are referred to as the control group.
At the end of the experiment, Victor would compare the behaviours of the students in the control group with the behaviour of those who were part of the experimental group to see if greeting reduced problem behaviours.

if the complement of an angle is 62 then find its supplement
Answer:
supplement = 152°
Step-by-step explanation:
If the complement is 62° , then
angle = 90° - 62° = 28° ( Complementary angles sum to 90° )
Supplementary angles sum to 180° , then supplement of 28° is
180° - 28° = 152°

-3(2+ k)- 6k = 6+ 3k
Answer:
solve for k, k=-1
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable
Answer:
k=-1
Step-by-step explanation:
First step: Distribute
Result: -6-3k-6k=6+3k
Second step: Combine like terms
Result: -6-9k=6+3k
Third step: Add 6 to both sides
Result: -9k=12+3k
Fourth step: Subtract 3k from both sides
Result: -12k=12
Final step: Divide by -12 to both sides
Result/Answer: k=-1

i could be wrong but i did it in my head , but the equation is right . just do that in order
Answer:
( 0.5, - 1 )
Step-by-step explanation:
So here is the equation:
x2 + x1 / 2 For the x coordinate
y2 + y1 / 2 For the y coordinate
x2 is 4 and x 1 is -3 whilst y2 is 2 and y1 is -4.
Thus:
4 + -3 / 2 = 0.5 x coordinate
2 + -4 / 2 = -1 y coordinate
So it becomes (0.5, -1)

What is the solution to the following system?
X+2y+z=9
X-y+3z=13
2z=10
Answer: x = 0; y = 2; z = 5
Step-by-step explanation:
x+2y+z=9
x-y+3z=13
2z=10
==
Start with the last equation: 2z = 10, therefore z = 5 [easy]
Let's rewrite the second equation with 1) z=5, and 2) rearrange to find x:
x-y+3z = 13
x - y +3*5 = 13
x = y-2
Now use the values for x [(y-2)] and y [5] in the first equation:
X+2y+z=9
(y-2) +2y + 5 = 9
3y +3 = 9
3y = 6
y = 2
Now that we have y [2] and z [5], let's use the first equation to solve for x:
x+2y+z=9
x + 4 + 5 = 9
x + 9 = 9
x = 0
====
Try the three values (x=0, y=2, and z=5) in any of the formulas. The result should/will equal the number shown.
