Aiden should use the unit kilogram(kg)
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out. We are told that a certan tile pattern had 6 triangles for every 20 squares.
The ratio that represents an equivalent ratio will be:
6 : 20 = 6/20 = 3/10 = 3:10
Answer:
1. Use the Adjacent and opposite side (Ignore the Hypotenuse)
Or use HERO'S FORMULA based on the information given
2. Area = 216cm^2
Step-by-step explanation:
There are three to four ways we can go about finding the area of a triangle. And a these would be dependent on the information given about the triangle.
From the question, you said the three side lengths are given. In such case, we employ the HERO FORMULA.
HERO FORMULA:
Area = √ s(s-a)(s-b)(s-c)
where s = 1/2(a + b + c)
a, b, c are the three sides
But since the question insisted that we use 1/2* base * height. Let's use our know of right angle to dissolve that.
A right angle triangle has three sides. The longest is always the Hypotenuse.
Let's take it this way.
Hypotenuse = 30cm
Opposite= 18cm
Adjacent = 24cm
Area = 1/2 * base * height
Area = 1/2 * 18 * 24
Area = 1/2 * 432
Area = 216cm^2
We ignored the longest side, (the Hypotenuse)
Use trigonometry ratio to solve the problem, the ratio we use is tan ratio
tan α =
plug in the numbers to find α
tan α =
tan α =
tan α =
tan α = 1.25
α = tan⁻¹ (1.25)
α = 51.340...
α = 51.3
The answer is second option
