Answer:

m<x = 48

m<y = 132

Step-by-step explanation:

Since x and y are supplementary angles, that means their sum is 180 degrees.

And we are given that y is 12 less than 3 times the measure of x.  With this information we can make a system of linear equations.

x + y = 180

y = 3x - 12

So now plug in the value of y into the first equation.

x + y = 180

x + (3x - 12) = 180

x + 3x = 192

4x = 192

x = 48

And then plug this computed value of x back into the first equation to find the measure of y.

x + y = 180

48 + y = 180

y = 180 - 48

y = 132

So the measures of the angles are as follows:

m<x = 48

m<y = 132

Cheers.

Please help me on a test 2 3/4 + 5 1/2
drek231 [11]

Answer: 8 1/4

Step-by-step explanation:

2 3/4 + 5 1/2 = ?

Least common denominator is 4

2 3/4 + 5 2/4 = ?

2(4)+3 = 11

5(4) + 2 = 22

so the equation becomes

11/4 + 22/4 = 33/4 = 8 1/4

Answer:

Reading bar graphs (multi-step) In a bar graph each bar represents a number. The following bar graph shows the number of seconds that different rides last at the fair. We can tell how long each ride lasts by matching the bar for that ride to the number it lines up with on the left.

Here is an example:

PLEASE ANSWER FAST
Dmitrij [34]
Hello there!

The answer to this question will be answer choice A.

When using the SAS postulate, we need two pairs of sides and the pair of the angles between those two sides to be congruent.

It is given that one pair of sides are congruent, along with a pair of congruent angles.

We want the congruent angle to be between two congruent sides, thus AC must be congruent to EC in order for these triangles to be proven congruent by the SAS postulate.

Hope this helps and have an awesome day! :)
