Answer:
Side length = 5.8 in
Perimeter = 29
Area = 58 in²
Step-by-step explanation:
✔️Find Side length using trigonometric ratio:
Angle at center of a pentagon is always 36° (we have measure of a full circle, 360, divided by 10 smaller triangles = 36°)
So:
Reference angle = 36°
Adjacent side = 4 in.
Opp = ½ of the side length of the polygon = x (let's represent this as x)
Thus, apply TOA:
Tan 36 = Opp/Adj
Tan 36 = x/4
4*Tan 36 = x
x ≈ 2.9 in (nearest tenth)
Side length = 2*x = 2*2.9 = 5.8 in
✔️Perimeter = 5*side length
Perimeter = 5*5.8 = 29 in
✔️Area = ½aP
Where,
a = 4 in
P = 29
Plug in the values
A = ½*4*29
A = 58 in²
- two acute angle=<JBC and <JBG
<JBC and <JBG(because these two angle are 45°)
by definition of acute angle any angle which is between 0°to 90° then it will acute angle
- two straight line=FH ,.AD
- two right angle=<GBD and <GBA
- two obtuse angle=<BCH and <BGF
Hello there! The answer is point C, which also happens to be answer C.
Our answer is required to be greater than 1.5 on the x-axis, but also less than -2.5 on the y-axis. By viewing the requirements for the x-axis, our only two relevant answers are points A and C. When looking at point A, however, it has a y-value of +4. Meanwhile, point C has a y-value of -3, which is less than -2.5. Therefore, our answer is point C. Hope this helps!
Imagine there is a right angle triangle formed with the 30 degree angle and the 10 cm side forming the hypotenuse. Now, you can use trigonometry to calculate the height of this triangle, which is the same as the height of this shape.
So sin(30) = height/10
So, height = 5 cm<span />
