What is the value of x?

Answer:

x=71

Step-by-step explanation:

Because of the side being marked 27, you know that the triangle is an isosceles triangle. That means that the other 2 angles would be congruent. To find the sum of the remaining angles, you need to subtract 38 by 180 degrees. (All of the angles in a triangle add up to 180) 180-38=142. Since we already know that the two remaining angles will be congruent, you take 142 and divide by 2 to get the final answer 71.

Answer:

x = 71°

Step-by-step explanation:

The triangle is clearly an isosceles triangle.

We know that all interior measures of a triangle must add up to 180°.

So: 180° - 38° =  142°

Because it is an isosceles triangle, the other two missing angles must be equal.

142° ÷ 2 = 71°

R varies directly as s. Find r when s=10 and k=4
nadezda [96]

Step-by-step explanation:

Since, r varies directly as s

\therefore \: r \:  \:  \alpha \:  \: s \\  \therefore \: r  = k s..(1) \:  \\ (k =  \: constant \: of \: proportionality ) \\ plug \: s = 10 \: and \: k = 4 \:  in \: equation \: (1) \\ r = 4 \times 10 \\ \huge \red{ \boxed{ \therefore \: r  =40}}

A company pays its employees a fixed base salary and a commission based on sales. The scatter plot below shows the total earning
Monica [59]

I'm assuming the question is

A company pays its employees a fixed base salary and a commission based on sales. The scatter plot shows the total earning of an employee of the company (y) based on sales (x):

Plot the ordered pairs 0, 10 and 100, 20 and 200, 30 and 300, 40 and 400, 50 and 500, 60

Which function best represents the data in the scatter plot? (1 point)

y = 0.1x + 10

y = 0.1x − 10

y = 0.1x + 1

y = 0.2x − 1

So thus your answer would be y = 0.1x + 10

How do i graph the lines when the equations aren’t in slope intercept form????
jekas [21]

Slope-Intercept Form: y=mx+b

Standard Form: ax+by=c

Point- Slope: (y-y1)= m(x-x1)

There are multiple answers to your question-

  1. If you are only missing b(the y-intercept) but are given a set of points, plug the points into x and y and solve for b.
  2. If you are only missing the slope(m) but are given a set of points, plug the points into x and y and solve for m.
  3. If you are given the standard form/point-slope form, change the equation to slope intercept form.
  4. If you are given an complete form(there is an x and y; no missing variables), but are not sure what it is, plug in some numbers in x to find y, then graph.

Plssss help fast and give a small explanation
Marrrta [24]

Answer: the area of the triangle is 23.4 cm²

Step-by-step explanation:

The given triangle is not a right angle triangle. Since two sides and one angle are known, we can either apply the Heron's formula or the Sine formula which is expressed as

Area of triangle = 1/2abSinC

Where a and b are the sides of the triangle and C is the given angle. Therefore,

Area = 1/2 × 8.2 × 6.4 × Sin63

Area = 1/2 × 8.2 × 6.4 × 0.8910

Area = 23.4 cm² to the nearest tenth.
