Answer:
The field will not fit
Step-by-step explanation:
To find the angle, we will use cosine rule;
c² = (a² + b² - 2abcosC)
C in this case is θ
Thus;
15² = (8² + 20² - 2(8 × 20)cos θ)
225 = (64 + 400 - 320cos θ)
464 - 225 = 320cos θ
cos θ = 239/320
θ = cos^(-1) 0.7469
θ = 41.68°
Thus angle is not less than 40° as recommended. Thus, the field will not fit.
Answer:
100
Step-by-step explanation:
120 + 130 + 10 = 260
360 - 260 = 100

</span>Finnegan needs to get the average of 70 in 4
tests in science to be able to make it to honour roll.
Find the lowest score he received on the fourth test if his first tests are 65,
60 and 92.
let x be the missing number
=> 65 + 60 + 92 + x / 4 = 70
=> 217 + x / 4 = 70
=> 217 + x = 4 x 70
=> 217 + x = 280
=> x = 280 – 217
=> x = 63
Thus the lowest score he get is 63.</span>
Use slope formula and get slope is -1
