Answer:

P=4x+9

Step-by-step explanation:

Basically, the problem is asking to make an triangle but without labeling its sides as number, but as algebraic expression.

So, let's say that all three sides are

AB=x+1\\BC=x+3\\AC=2x+5\\

Now, remember that the perimeter is the sum of all sides of a figure, so in this case would be

P=(x+1)+(x+3)+(2x+5)

To simplify this expression, we just need to reduce like terms as follows

P=(x+1)+(x+3)+(2x+5)\\P=(x+x+2x)+(1+3+5)\\P=4x+9

Therefore, the simplified expression of the perimeter is

P=4x+9

The image attached shows the triangle we used.

The diagram shows a logo​
Charra [1.4K]

Answer/Step-by-step explanation:

✔️Find EC using Cosine Rule:

EC² = DC² + DE² - 2*DC*DE*cos(D)

EC² = 27² + 14² - 2*27*14*cos(32)

EC² = 925 - 756*cos(32)

EC² = 283.875639

EC = √283.875639

EC = 16.85 cm

✔️Find the area of ∆DCE:

Area = ½*14*27*sin(32)

Area of ∆DCE = 100.15 cm²

✔️Since ∆DCE and ∆ABE are congruent, therefore,

Area of ∆ABE = 100.15 cm²

✔️Find the area of the sector:

Area of sector = 105/360*π*16.85²

Area = 260.16 cm² (nearest tenth)

✔️Therefore,

Area of the logo = 100.15 + 100.15 + 260.16 = 460.46 ≈ 460 cm² (to 2 S.F)
