- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] tan∅ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Define</u>
We have a right triangle triangle. We can use trig to find the missing length.
<u>Step 2: Identify Variables</u>
<em>POV from the angle measure</em>
Angle = 64°
Opposite = 13
Adjacent = <em>x</em>
<em />
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute: tan64° = 13/x
- Multiply <em>x </em>on both sides: xtan64° = 13
- Isolate <em>x</em>: x = 13/tan64°
- Evaluate: x = 6.34052
Answer:
21
Step-by-step explanation:
Nope.
I don't really know how to explain this in a way that will make sense to you, but just look at the numbers:
Area 8 x 3= 24 units²
Per 16+6= 22 unites
Area 12 x 2 = 24 units²
per 24+4 = 28 units
See? the area is the same but the perimeter is different.

Answer: 1747067797/2500000000
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
0.6988271188=0.6988271188/1
Multiply to remove 10 decimal places. Here, you multiply top and bottom by 10 to the 10 power = 10000000000
0.6988271188/1 * 10000000000/10000000000 * 6988271188/10000000000
