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

Answer:
Step-by-step explanation:
Answer: Girls: 20
Boys: 30
Step-by-step explanation: 40% of 50 is 20, which means there are 20 girls.
Subtract 50-20 to get the number of boys, which is 30.
Answer: the answer is 54
Step-by-step explanation: The error in the expression was that it was multiplied by 1 so it can't be one unless it was also 1 and it's not it is 54.
Answer:
The correct option is the graph on the bottom right whose screen grab is attached (please find)
Step-by-step explanation:
The information given are;
The required model height for the designed clothes should be less than or equal to 5 feet 10 inches
The equation for the variance in height is of the straight line form;
y = m·x + c
Where x is the height in inches
Given that the maximum height allowable is 70 inches, when x = 0 we have;
y = m·0 + c = 70
Therefore, c = 70
Also when the variance = 0 the maximum height should be 70 which gives the x and y-intercepts as 70 and 70 respectively such that m = 1
The equation becomes;
y ≤ x + 70
Also when x > 70, we have y ≤
-x + 70
with a slope of -1
To graph an inequality, we shade the area of interest which in this case of ≤ is on the lower side of the solid line and the graph that can be used to determine the possible variance levels that would result in an acceptable height is the bottom right inequality graph.
