How do you find the perimeter

Mathematics

The perimeter is 86 m.

When you add the 18 with the 11, you get the length of the bottom side, which is 29. When you add the nine and the 6, you get the length of the left side, which is 15. Now add everything together.

18 + 6 + 11 + 9 + 29 + 15 = 86 m

Hope I helped. Good luck!! : )

Pls help me with 19,20 pls thx and show me how u did it

Anastasy [175]

For number 19:
"at least 150" means either 150 ≤ ? or ? ≥ 150

plus 3 so +3x

The answer would be 150 ≤ 100 + 3x

Number 20:

A is at -2.5. The inverse is the opposite so 2.5

Suppose you want to draw a rectangle where the width is 7 inches less than the length and the diagonal is 2 inches longer than t

IrinaK [193]

The diagonal of a rectangle is:
d ^ 2 = w ^ 2 + l ^ 2
Where,
w: width
l: long
Substituting values we have:
(l + 2) ^ 2 = (l-7) ^ 2 + l ^ 2
Rewriting we have:
l ^ 2 + 4l + 4 = l ^ 2 -14l + 49 + l ^ 2
l ^ 2 -14l + 49 - 4l - 4 = 0
l ^ 2 -18l + 45 = 0
(l-15) (l-3) = 0
The solutions are:
l = 15
l = 3
The viable solution is:
l = 15
Thus, the width is:
w = l-7
w = 15-7
w = 8
Answer:
the dimensions of the rectangle are:
l = 15
w = 8

Analyze the diagram below and complete the instructions that follow.<br><br> Find m

Stells [14]

Answer:

D. 70.53

Step-by-step explanation:

To solve this problem, one must use the right angle trigonometric rations. These ratios can be used to describe the ratio between the sides and an angle in a right triangle. Please note, each side is named relative to the angle that one is looking at, thus the same side can acquire different names based on the angle one uses to describe it. The trigonometric ratios are the following:

$sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}$

In this case, one is asked to find the measure of (<CBA), one is given the hypotenuse (the side opposite the right angle), and the side adjacent to this angle. Therefore, one should use the cosine (cos) function to find this angle.

$cos(\theta)=\frac{adjacent}{hypotenuse}$

Substitute,

$cos(CBA) = \frac{3}{9}$

Simplify

$cos(CBA) = \frac{1}{3}$

Inverse operations,

$CBA=cos^-1(\frac{1}{3})$

Compute,

m<CBA = 70.53
