In ΔNOP, p = 2.5 cm, n = 2.3 cm and ∠O=71°. Find the area of ΔNOP, to the nearest 10th of a square centimeter.
1 answer:
The area of the triangle is expressed as 2.718cm²
<h3>Area of a triangle</h3>
The formula for calculating the area of a triangle is expressed as:
A = 0.5absinФ
- a and b are the sides
- Ф is the angle
Given the following
- p = 2.5 cm
- n = 2.3 cm and;
- ∠O=71°
Substitute the given parameters to have:
Area = 0.5(2.5)(2.3)sin71
Area = 2.718cm²
Hence the area of the triangle is expressed as 2.718cm²

Step-by-step explanation:
Divide the triangle into 2 congruent right angle triangles
With hypotenuse: 2
Base: 2/2 = 1
Using pythagoras theorem
2² = 1² + h²
h² = 3
h = sqrt(3)
h = 1.732050808
The problem gives you X, so replace X witht he given vaule and solve for y:
y = -0.1x^2 + 4X
X = 40
y = -0.1(40)^2 +4(40)
y = -0.1(1600) + 160
y = -160 + 160
y = 0
Answer:
9x -45
Step-by-step explanation:
The distributive property tells you the factor outside parentheses applies to each of the terms inside parentheses:
-9(-x +5) = (-9)(-x) +(-9)(5)
= 9x -45
