Answer:

AE Measure: 23.36 units

Step-by-step explanation:

BA: 20cm

BC:20cm

BE:10cm CE: 10cm

a^2 +b^2=c^2

BE^2 +BA^2 = AE^2

√100 + √400 = √500

AE^2 = √500 = 23.36

AE = 23.36 unit

Step-by-step explanation:

As ABCD is a square , BC = 20 cm

BE = 20/2 = 10 cm

Also , angle B = 90⁰

By pythagoras theorem :

AE² = 20² + 10²

AE² = 400 + 100

AE² = 500

AE = 10√5 cm

work out the total area of triangle ABC. calculate the area of AC. sides are:8.2cm and 13.5cm and angle 81 degrees

umka2103 [35]

Answer:

54.67 cm²

Step-by-step explanation:

Given that the two sides of Δ ABC are 8.2 cm and 13.5 cm and the angle included by those sides is 81°.

Let, b = 8.2 cm and c = 13.5 cm and ∠ A = 81°

Hence, area of triangle ABC, Δ = $\frac{1}{2} bc \sin A$

⇒ Δ = $\frac{1}{2} bc \sin 81$

⇒ Δ = $\frac{8.2 \times 13.5 \times \sin 81}{2}$

⇒ Δ = 54.67 cm² (Answer)

Answer:

If the diameter is 12 inches, the radius is 6 inches, because the radius is half the diameter. When you fold the circle in half, the resulting figure has half the area.
