We are given with the points (-1,4), (2,7) and (1,5) as the sides of the triangle. The area of the triangle can be determined by determining first the length of the sides. Via distance formula, the sides are 3 sqrt 2, sqrt 5 and sqrt 5. The perimeter thus is equal to 8.71 units
Answer:
0.75°C
Step-by-step explanation:
Person A Person B Person C
-3 4 8
-1 -4 -2
0 2 5
2 -3 1
To get Fatima mean value, we have to add all the given values together
= - 3 + 4 + 8 - 1 - 4 - 2 + 0 + 2 + 5 + 2 - 3 + 1
= 9
Estimate is 9 deg above Actual Temperature in 12 readings
The formula for our Mean Value will be, the added values divided by actual temperatures
Added values = 9
Actual temperature = 12
Mean value = 9 ÷ 12 = 0.75°C above actual Temperature
Area of a trapezoid:
A = 1/2 * ( b 1 + b 2) *h
b 1 = 8 m, b 2 = 1 m, h = 5 m;
A = 1/2*( 8 + 1 ) * 5 = 1/2 * 45 = 22.5
Answer: B ) 22.5 m²
Angle 4 equals 34 degrees since angle 2 and 4 are opposite angles and opposite angles are congruent
