Given the figure below find the values of x and z <br> (12x +2)°<br> 94°<br> z°
MAXImum [283]

Answer:

z = 94

x = 7

Step-by-step explanation:

The angle with a measure of 94° and the angle labeled "z" are vertical angles

Vertical angles are congruent ( equal to each other )

Which means that because "z"s vertical angle = 94° z also equals 94°

The angle labeled with the expression ( 12x + 2 ) and the angle with a measure of 94° are supplementary angles

Supplementary angles add up to equal 180

Hence, 94 + 12x + 2 = 180

                        ^ (Note that this is the equation we will use to solve for x )

Now we solve for x

94 + 12x + 2 = 180  

step 1 combine like terms

94 + 2 = 96

we now have 180 = 96 + 12x

step 2 subtract 96 from each side

180 - 96 = 84

96 - 96 cancels out

we now have 84 = 12x

step 3 divide each side by 12

84 / 12 = 7

12x / 12 = x

we're left with x = 12

Does anyone know the answer to this?
bezimeni [28]

Hey there!


First, let's find s:

s = (5 + 6 + 7) /2 = 9


Second, let's plug in the numbers into the formula:

A = \sqrt{9(9-7)(9-5)(9-6)}


Third, let's simplify the numbers to get one number under the square root:

A = [tex]\sqrt{216}


Fourth, we'll find the square root of 216 to get the area:

A = 14.697


Therefore, your answer is A.


Hope this helps!! :)

Answer:

88 square inches

Step-by-step explanation:

if the entire square was shaded it would be 14 x 12  (as best as i can see)

the "cut out" or white part of the square is 8 x 10

Entire squre - cutout white part

14 x 12     -  8 x 10

168 - 80

88 sq in
