Angles RTG and GTU are adjacent angles. If m∠RTG=5.8° and m∠GTU=113.6°, what is m∠RTU in degrees?

Answers

Answer 1

If m∠RTG = 5.8° and m∠GTU = 113.6°. Then the measure of the angle ∠RTU will be 119.4°.

What is an angle?

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Adjacent angle - In math, two points are nearby in the event that they have a typical side and a typical vertex.

Angles RTG and GTU are adjacent angles. If m∠RTG = 5.8° and m∠GTU = 113.6°.

∠RTU = ∠RTG + ∠GTU

∠RTU = 5.8° + 113.6°

∠RTU = 119.4°

The measure of the angle ∠RTU will be 119.4°.

bob can do a job in 5 hours while bill can do the same job in 8 hours. how many hours would it take them, working together, to do this job?

Answers

Hours taken by Bob and Bill if they work together is 3 1/13.

Here it is given that Bob can do a job in 5 hours and Bill can do the job in 8 hours.

We have to find the time taken by both to do the work if done together.

Time ratio of Bob and Bill = 5: 8

Efficiency of Bob and Bill = 8: 5

Total amount of work done = 5× 8 = 8× 5 = 40

The total efficiency of Bob and Bill = 13

Hours took by both bob and bill to do the work if done together = 40/13

                                                                                                              = 3 [tex]\frac{1}{13}[/tex]

What is a Triangle?

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.

The triangle has interior angles are:

(2x)°, (3x)° and (4x)°

As we know that the sum of interior angles is 180 degrees in the triangle.

According to the given figure,

(2x)° + (3x)° + (4x)° = 180°

Apply the addition operation in the above equation,

9x = 180

x = 180/9

x = 20°

Thus, The triangle has interior angles are:

The equation of the absolute value function graph is: y = |x - 3| + 5.

What is the Equation of the Absolute Value Function?

The equation of the absolute value function can be written in the vertex form as y = a|x – h| + k, where:

The vertex of the graph = (h, k)The value of a is determined by whether the graph opens up or opens down.The horizontal translation factor, which determines how far left or right the parent function is translated = hThe vertical translation factor, which determines how far up or down the parent function is translated = k.

From the given graph, we have the following:

(h, k) = (3, 5) [the vertex]

Substitute the values into the equation, y = a|x – h| + k:

y = a|x - 3| + 5

A point on the graph is (2, 6). To find the value of a, substitute (x, y) = (2, 6) into y = a|x - 3| + 5:

6 = a|2 - 3| + 5

6 = a|-1| + 5

6 = a + 5

6 - 5 = a

1 = a

a = 1

To write the equation of the graph, substitute a = 1 into y = a|x - 3| + 5:

y = 1|x - 3| + 5

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line is given by:

y = mx + c

The line passes through:

(-5, 19) and (5, 13)

So,

m = (13 - 19) / (5 + 5)

m = -6/10

m = -3/5

Now,

(5, 13) = (x, y)

13 = (-3/5) x 5 + c

13= -3 + c

13 + 3 = c

c = 16

Plug x = 0 into the equation
