Answer:

To find cosθ, use the formula for the area of a triangle i.e. AREA=1/2 x a x b x sinC.=> For this case: 15= 1/2 x 10 x 5 x sinC to find sinC.=> SinC = 3/5 thus, Arcsin(3/5)=+- 4/5 or +-0.8

To find the exact length of BC, use the cosine rule.=> c(sq)=a(sq)+b(sq)-2abCosC=> c(sq)=10(sq)+5(sq)-2(10)(5)(+-4/5)=> c(sq)= Square root of 205

Ierofanga [76]

Answer: 6/5

Step-by-step explanation:

Given the points:

(–2, –1) and (3, 5)

x1 = - 2 ; y1 = - 1 ; x2 = 3 ; y2 = 5

Slope is the change in y divided change in x

Slope = change in y / change in x

Slope = (y2 - y1) / (x2 - x1)

Slope = (5 - (-1)) / (3 - (-2))

Slope = (5 + 1) / 3 +2

Slope = 6 / 5

SOLVE: 23 (3 + 48) - x =
Damm [24]

Answer: -x + 1173

Step-by-step explanation:

23 (3 + 48) - x

23 x 3 = 69 and 23 x 48 = 1104

(69 + 1104) - x

69 + 1104 = 1173

1173 = -x or -x = 1173
