Answer:

  (d)  -11

Step-by-step explanation:

The sum of the acute angles of a right triangle is 90°. (That makes the sum of all angles be 180°, as it is for any triangle.)

  65° +(36 +x)° = 90°

  x = 90 -101 . . . . . . . . divide by °, subtract 101

  x = -11

The measure of one angle of a parallelogram is 40 more than 3 times another. Find the measure of each angle.
tankabanditka [31]
Two angles in the same parallelogram must either be equal or else add up to 180 degrees.  These two are obviously not equal, so they must add up to 180.

A + B = 180
A = 180 - B  (we'll use this in just a second)

A = 3B + 40

180 - B = 3B + 40

Add 'B' to each side:

180 = 4B + 40

Subtract 40 from each side:

140 = 4B

Divide each side by 4 :

<u>35 = B</u>

A = 180 - B = <u>145</u>

I can’t figure out how to do a and b for 33
Monica [59]
A)
original rectangle P = 2(w+l)
so 
18 = 2(w+l) (1)

new rectangle 
doubling width w, so its 2w
tripling length l, so its 3l
46 = 2(2w + 3l) (2)

now you have
18 = 2(w+l) (1)
9 = w + l so w = 9 - l

46 = 2(2w + 3l) (2)
23 = 2w + 3l

substitute w = 9 - l into 23 = 2w + 3l
23 = 2w + 3l
23 = 2(9 - l) + 3l
23 = 18 - 2l + 3 l
23 - 18 = l
5 = l or l = 5
w = 9 - l = 9 - 5 = 4

answer
original rectangle, length = 5 in and width = 4 in

b)new rectangle
length = 3l = 3(5) = 15 in
width = 2w = 2(4) = 8 in
