I think C because A and D are Vertically Opposite angles and B is Complimentary angles

The answer is B. 1 and 3

Adjacent angles share a vertex and a side. These two angles, 1 and 3, are both adjacent and supplementary (sum to 180 degrees).

In a right triangle the measures of the two smaller angles are (3x+6) and (2x+1) find the measure of the smaller angle in the tr

Well since the triangle is right angled you know that the given angles sum to 90........(angle sum of a triangle 180, 1 angle = 90) so you can say 3x + 6 + 2x - 1 = 90 or 5x - 5 = 90 now solve for x. the smaller angle will be 2x - 1 so substitute your answer for x and you'll have the measure of the smaller angle. hope that helps

Look at the Picture. Look at the Picture.

Answer:

325 square inches

Step-by-step explanation:

Consider the attachment below for further reference. Ideally we would split this figure into parts, and solve as demonstrated by the attachment. I have labeled each rectangle as rectangle 1, rectangle 2, rectangle 3 etc. ;

$Rectangle 1 Area = 17 in * 5 in = 85 square in\\Rectangle 2 Area = ( 17 in - 5 in ) * 14 in = 168 square in,\\Rectangle 3 Area = ( 12 in - 3 in ) * 8 in = 72 square in\\\\Total Area = 85 + 168 + 72 = 325 square inches$

What is the difference between 5/6 and 1/5

Slav-nsk [51]

Hey there!

The answer is $\frac{19}{30}$

To solve this we use subtraction, because "the difference" represents subtraction, so:

$\frac{5}{6} - \frac{1}{5}$

Now, we must find a common denominator, and we can see that $6$ and $5$ both go into $30$ . To get to $30$ , we multiplied the first fraction by 5 and the second by 6, so we now have:
