In ΔMNO, the measure of ∠O=90°, the measure of ∠N=70°, and OM = 3.3 feet. Find the length of MN to the nearest tenth of a foot.

Aleks04 [339]

Answer:

Side MN = 3.5

Step-by-step explanation:

Side NO = 1.2011

Side OM = 3.3

Side MN = 3.51179

Angle ∠M = 20° = 0.34907 rad = π/9

Angle ∠N = 70° = 1.22173 rad = 7/18π

Angle ∠O = 90° = 1.5708 rad = π/2

Find the distance (-4,6) and (3,-7)

forsale [732]

Answer:

Distance ≈ 14.8

Step-by-step explanation:

<u>Calculate the distance (d) using the distance formula</u>

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 4, 6) and (x₂, y₂ ) = (3, - 7)

Hope this helps!!!!

If Triangle ABC is congruent to Triangle SRT, find the possible value(s) for x

Eva8 [605]

Answer:

x = 2 or x = -3

Step-by-step explanation:

Given that ∆ABC ≅ ∆SRT, it follows that their corresponding side lengths are congruent to each other.

Thus:

$RT = BC$

$(x^2 + x) = 6$

Solve for x

$x^2 + x = 6$

Subtract 6 from each side

$x^2 + x - 6 = 6 - 6$

$x^2 + x - 6 = 0$

Factorise

$x^2 + 3x - 2x - 6 = 0$

$x(x + 3) -2(x + 3)$

$(x - 2)(x + 3)$

x = 2 or x = -3
