1. classify the triangle by its sides

Mathematics

The first one is isosceles because it has two side lengths that are the same, C.
The missing angle measure is 35° because all of them together should add up to 180° and 105+40+35=180, A.
The possible lengths for the third triangle e are in between 7, and 17. This is because the possible side lengths are in between adding the two side lengths together, (12+5=17) and subtracting the littler side by the bigger side. (12-5=7)

Find the x and y intercepts<br> c) x + 3y - 12=0
mojhsa [17]
To get x intercept:
let y=0,x➖12=0,x=12
so x intercept point (12,0)
To get y intercept:
let x=0,3y➖12=0,y=4
so y intercept point (0,4)

Select from the drop-down menus to correctly complete each statement. −20&gt;−21 −19&gt;−20 −21 is located to the of −20 on a nu
LekaFEV [45]

Answer:

  left, right

Step-by-step explanation:

If you use the < or ≤ symbol to compare the numbers, their left-right order is the same as on the number line. Here, we would write the ordering as ...

  -21 < -20 < -19

So, we see that ...

  -21 is <em>left</em> of -20 on the number line

  -19 is <em>right</em> of -20 on the number line

Instructions: Find the missing side. Round your answer to the nearest
ch4aika [34]

Answer:

Step-by-step explanation:

Tan(51) = opposite / adjacent

The adjacent side makes up the reference angle (51o)

The opposite side is not part of the reference angle

adjacent side = x

opposite side = 16

Tan(51) = 16 / x              Multiply both sides by x

x * Tan(51) = 16            Divide by tan 51

x = 16 / tan(51)

tan(51) = 1.2349

x = 16 / 1.2349

x = 12.96

If (k, 4) is a point<br> on the graph of the equation 4x + 2y=4, what is the<br> value of k?
zmey [24]

Answer

k = -1

Step-by-step explanation:

First we turn the equation into y = mx+b format then we we can plug in the value y= 4 and get 4 = -2x + 2

subtract two from both sides so 2= -2x divide btoh sides by 2 and get x = -1
