A = 50.24
To find the area of a circle we can use the following equation
Answer:
y=27.8
Step-by-step explanation:
- 8^2=17^2+16^2-2(16)(17)cosY
- 8^2-17^2-16^2/-2(17)(16)=cosY
- -481/-544=cosY
- 0.8842=cosY
- Y is about 27.8
Answer:
a. ∆EGF ≅ ∆EGD
Step-by-step explanation:
Congruent triangles would have the same side lengths and the same measure of angles.
From the figure given:
EG in ∆EGF ≅ EG in ∆EGD
GF in ∆EGF ≅ GD in ∆EGD, also
EF ≅ ED.
The three angles in ∆EFG are also congruent to the three angles in ∆EGD.
Therefore, ∆EGD is congruent to ∆EGF.
∆EGF ≅ ∆EGD
Answer:
x=5
y=30
x=15
Step-by-step explanation:
y=3x=15, then x=15/3, x=5
x=10, then y=3x=3*10=30
y=3x=45, then x=45/3, x=15
Answer:
The answer to your question is 757.1 cm²
Step-by-step explanation:
Data
Ratio 1: 1.618
long side = 35 cm
Area = ?
Process
1.- Use proportions to solve this problem
1 : 1.618 :: x : 35
x = (35 x 1) / 1.618
x = 35 / 1.618
x = 21.63
2.- Calculate the area of the rectangle
Area = base x height
Area = 35 x 21.63
Area = 757.1 cm²
