4/5 and 40/50 are both equivalent
Answer:
319
Step-by-step explanation:
\text{Area of a Triangle}\rightarrow \text{S.A.S.}
Area of a Triangle→S.A.S.
\text{Area}=\frac{1}{2}ab\sin C
Area=
2
1
absinC
From reference sheet.
\text{Area}=\frac{1}{2}(12)(55)\sin 75
Area=
2
1
(12)(55)sin75
Plug in values.
\text{Area}\approx318.756\approx 319
Area≈318.756≈31
Answer: 54 cm^2
Step-by-step explanation:
The area of a triangle is base*height/2.
To find the missing side of this triangle we can use pythagorean theroem. Let the unknown side = x
15^2 = 12^2+x^2
225 = 144+x^2
x^2 = 81
x = 9
Area = BH/2
Area = 9*12/2
Area = 54 cm^2
divide completions by percentage
345 / 0.60 = 575 pass attempts
