Answer:
Step-by-step explanation:
A triangle whose sides are 5-12-13 is a right angle triangle because the sides form a Pythagoras triple. This means that
Hypotenuse² = opposite side² + adjacent side²
If hypotenuse = 13,
Opposite side = 12, then we can determine one acute angle by applying the sine trigonometric ratio
Sin θ = opposite side/adjacent side
Sin θ = 12/13 = 0.923
θ = Sin^-1(0.923) = 67.4°
The other acute angle is
90 - 67.4 = 22.6°
For 9-12-15 triangle
Sin θ = 12/15 = 0.8
θ = Sin^-1(0.8) = 53.1°
The other acute angle is
90 - 53.1 = 36.9°
For 13- 14-15 triangle,
Sin θ = 14/15 = 0.933
θ = Sin^-1(0.933) = 68.9°
The other acute angle is
90 - 68.9 = 21.1°
Another example would be 3-4-5
Sin θ = 4/5 = 0.933
θ = Sin^-1(0.8) = 53.1°
The other acute angle is
90 - 53.1 = 36.9°
Answer:
area of a circle is equal to pi × radius square. pi*r^2 ( pi = 3.14 or 22/7)
Answer:
-3.7 is the answer because it it more positive than -4.3
Step-by-step explanation:
X/360 * 3.14(6^2) = 45.27
When solved, x is about 144.1 when rounding to nearest the two decimal places.
The answer is 144.1 (I think)
Answer:
<em>Well, Your best answer will be is </em><em>51° </em><em>Because, </em>
<em>
Here, given a = 7 in
</em>
<em>b = 9 in
</em>
<em>
</em>
<em>∠B = 95°
</em>
<em>
</em><em>So, The best answer will be is 51°</em>
<em>Good Luck!</em>
