Step-by-step explanation:
sin(5π/4)
2π=360°
4π=720°
1/4π=360/4=90°
sin(810)=sin(90°)=1
Answer:
Step-by-step explanation:
<u>Area of ΔABC is:</u>
<u>We have:</u>
<u>Find CD using Pythagorean:</u>
- CD² = AC² - AD² ⇒ CD² = 3² - 1.8² ⇒ CD² = 5.76 ⇒ CD = √5.76 = 2.4
<u>Find DB using the following identity, coming from ratios of corresponding sides of similar triangles:</u>
- CD² = AD*DB
- 5.76 = 1.8*DB
- DB = 5.76/1.8
- DB = 3.2
<u>Find AB:</u>
- AB = AD + DB
- AB = 1.8 + 3.2
- AB = 5
<u>Find the area of ΔABC:</u>
- A = 1/2*5*2.4
- A = 6 units²
Equation F can be written as 2d + 1 = 3d + 7
