Answer:
Step-by-step explanation:
law of sines
Sin(A) / a = Sin(B)/b
where A = 24
a=BC
B= 59
b =AB
then
Sin(24)/a =Sin(59)/19
0.4067366 / a = 0.8571673 / 19
0.4067366 / a = 0.045114
0.4067366 / 0.045114 = a
9.015 = a
BC = 9.0 mi
Answer: perimeter of triangle ABC to the nearest tenth = 27.4
Step-by-step explanation: Given that
vertices are
A(- 4, 5), B(- 4, - 4) , and C(3,-4)
Length AB = root( [-4-5]^2 + [-4+4]^2)
Length AB = sqr(9^2) = 9
Length AC = root( [-4-5]^2 + [3+4]^2)
Length AC = sqr( 9^2 + 7^2)
Length AC = sqr(130) = 11.4
Length BC = root( [-4+4]^2 + [3+4]^2)
Length BC = sqr( 7^2) = 7
Perimeter = 9 + 11.4 + 7 = 27.4
Answer:A:3/24
Step-by-step explanation:
It’s basic math
Answer:
<em>Perimeter = 20.6cm to 1dp = 20.60cm to 2dp</em>
<em>Area = Base = 8.6/2 = 4.3 x 4.069 = 17.5cm^2</em>
<em>Height is found 4.07 cos( 54.47deg) 5/8.6 = 4.069cm</em>
Step-by-step explanation:
<em>Right angle side triangle, sides </em>
<em>= MN =8.6cm </em>
<em>= NP=5cm </em>
<em>= PM=7cm </em>
<em>= 25sq + 49sq = 74sq</em>
<em>MN^2 =√74 = 8.60232526704 = 8.6cm</em>
<em>P = 8.6 + 5 + 7 = 20.6cm </em>
Answer:
Step-by-step explanation:
y intercept
To find the y intercept, make x = 0
2(0) + y = - 6 zero times anything is 0
0 + y = -6
The y intercept is (0,-6)
x intercept
The x intercept happens when y = 0
2x + 0 = -6 zero added to anything = whatever you started with.
2x = - 6 Divide by 2
2x/2 = -6/2 Do the division
x = - 3
The x intercept = (-3,0)
