Triangle RST is an isosceles triangle.
Triangle RST is a scalene triangle.
Triangle RST is a right triangle.
Triangle RST is an equilateral triangle.
Answer:
RST is an isosceles triangle
Step-by-step explanation:.
Required
Determine what type of triangle, is RST.
First, we need to determine the angles in RST
Angle on a straight line is 180°.
So, if <mTS = 130°
Then,
<STR = 180° - 130°
<STR = 50°
Similarly,
<TSR = 180° - 130°
<TSR = 50°
The sum of angles in a triangle is 180°.
So:
<TSR + <STR + <TRS = 180°
50 + 50 + <TSR = 180°
100 + <TSR = 180°
<TSR = 180° - 100°
<TSR = 80°
Hence, the three angles of the triangle are: 50°, 50° and 80°
When just two angles of a triangle are equal; such triangle is referred to as an isosceles triangle
Hence, option A answers the question.
What is the sum of the exterior angles of a 54-gon?
Answer: The sum of the exterior angles of a 54-gon should be 360°.
Step-by-step explanation:
A polygon is a closed figure made up of straight lines like triangle (3-gon) , quadrilateral (4-gon) , square(4-gon), pentagon (5-gon) , octagon(8-gon) etc.
The sum of exterior angles of any polygon with n sides ( or n-gon ) is always 360 degrees.
A 54-gon is a polygon with 54 sides.
Therefore , the sum of the exterior angles of a 54-gon should be 360°.

Maya needs to lease out a music studio to record her new album. The studio charges an initial studio-use fee plus an hourly fee for each hour in the studio. The total amount of money Maya would have to pay to use the studio for tt hours can be determined using the equation P=50t+100.P=50t+100. What is the yy-intercept of the equation and what is its interpretation in the context of the problem?
Answer:
The y intercept is 100. that means she needs to pay a $100 base fee for the rental.

2 Why is adding 6, 10, and 5 to a number the same as
adding 21 to that number?
Answer:because 6, 10, and 5 equal 21
Adding 6, 10, and 5 to a number the same as adding 21 to that number, because sum of 6, 10, and 5 is 21.
Given that, adding 6, 10, and 5 to a number the same as adding 21 to that number.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the unknown number be x.
Add 6, 10, and 5 to x, we get x+6+10+5 = x+21
Add 21 to x = x+21
So equation is x+21 = x+21
Therefore, adding 6, 10, and 5 to a number the same as adding 21 to that number, because sum of 6, 10, and 5 is 21.

Step-by-step explanation:
The missing reasons for the given two column proof are respectively;
Reason 2; Definition of Supplementary angles
Reason 3; Substitution Property of Equality
Reason 4;Subtraction Property of Equality
How to complete the two column proof?From the two column proof, we are given that;
m∠2 = m∠3
Now, for m∠1 + m∠2 = 180°, we see that m∠1 and m∠2 are on a straight line and we know that angles on a straight line sum up to 180°. Thus, the reason is because they are supplementary angles.
Similarly, m∠3 and m∠4 are on a straight line and as such;
m∠3 + m∠4 = 180°
m∠1 + m∠2 = m∠3 + m∠4. This is true because of substitution property of equality.
Lastly, since m∠2 = m∠3, then it means that they will cancel out in the statement 3 and as such we now have;
m∠1 = m∠4. The reason is subtraction property of equality

Answer:
The absolute maximum value of f on [-2, 4] occurs at x = 4.
Step-by-step explanation:
We know that the absolute maximum value of f(x) on this interval will occur at either a critical point or an endpoint. The critical points are any point where f'(x) is either equal to zero or not defined. Since f is a polynomial, f'(x) = 3x^2 - 6x is always defined, but is equal to zero at x = 0 and x = 2. We can check the value of f(x) at each critical point and endpoint:
f(-2) = -8
f(0) = 12
f(2) = 8
f(4) = 28
Therefore, f has an absolute maximum value of 28 on the closed interval [-2, 4], which occurs when x = 4.
f(x) = x^3-15x^2+41x-15

A boat can travel 20 miles on 10 gallons of gasoline. How much gasoline will it need to go 34 miles?
Answer:
20 divided by 10 is 2 so for every 2 miles it travels it uses 1 gallon of gasoline. 20 + 14 is 34 so you divide 14 by 2 to get 7. then you add 10+7 to get 17. it will take 17 gallons of gasoline to go 34 miles
