Find the value of x. Show all work.

x = -8°

Step-by-step explanation:

Angle 2

Since the triangle is isosceles, Angle 2 is the same as the missing angle

So angle 2 would be:

180 - 34 = 2(angle 2)

So 146 = 2(x + 81)

146 = 2x + 162

146 - 2x = 162

-2x = 16

x = -8

Check

146 = 2(-8+81)

146 = 2(73)

146 = 146

Correct!

Answer and Step-by-step explanation:

We are given an isosceles triangle, shown by the fact that there are two red marks on two sides, indicating that the sides are congruent in length, which means the base angles are congruent as well.

Add the angles together and equal it to 180.

34 + x + 81 + x + 81 = 180

Simplify.

115 + 2x = 180

Subtract 115 from both sides of the equation.

2x = 65

Divide both sides of the equation by 2.

x = 32.5 is the answer.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
