Because the triangle is an equilateral triangle, this means that all angles are 60 degrees, and all sides are the same length. The question states that line RT bisects line QS at a perpendicular angle.
Line RT bisects angle R as a result. When a line bisects an angle, the angle is divided by 2. Find the new angle of R:
The new angle of R is 30 for both triangles.
The square denotes a right angle, which is 90 degrees. We'll focus on triangle QRT, as it is the triangle listed in most answers.
Two of its angles have measures of 30 degrees and 90 degrees. A triangle's internal angles must all add up to 180. To find the missing angle, set up the following equation where the missing angle = x:
Subtract 120 from both sides to get x by itself:
The three angles of triangle QRT are 30, 60, and 90, making it a 30-60-90 triangle.
The answer is <span>
A. QRT is a 30-60-90 triangle.</span>
Here's a couple of ideas.
1) Use concept of rational numbers.
Start by assigning 2 variables with a square root, representing each student.
Then multiply the 2 variables together resulting in a whole number. (canceling the square root)
Then say that being by yourself is irrational. But working together is rational.
2) Set up a linear equation to show how the more they work together the higher their grades will be.
For 8th grade a simple one is all that is needed.
where t is hours working together.
Provide a graph or table demonstrating the positive slope.
Good luck
Answer:
H
Step-by-step explanation:
Area of a square is given as 16 unit²
Since formula of square is
A=l²
16=l²
l=√16
=4
Answer:
3rd one. is right
Step-by-step explanation:
Answer:x=11
65.25x + 1063.50= 1781.25
To solve this equation, subtract the rental cost of the bus to get $717.75.
Now the equation should be 65.25x= 717.75
Divide both sides by 65.25, and you should get that x = 11. That’s your finally answer!
