In ΔNOP, the measure of ∠P=90°, the measure of ∠N=59°, and PN = 7.4 feet. Find the length of OP to the nearest tenth of a foot.
lina2011 [118]

Answer:

12.3 feet.

Step-by-step explanation:

As we are given that \triangle NOP is an right angled triangle.

\angle P = 90 ^\circ \\\angle N = 59 ^\circ\\Side\ PN = 7.4 \text{ feet}

And we have to find out the value of side OP to the nearest tenth of a foot by rounding off the value as seen in the attached figure as well.

By using Trigonometric functions in a right angled \triangle, we know that:

tan \theta = \frac{Perpendicular}{Base}

Here, \theta is \angle N, Perpendicular is side <em>OP</em> and Base is side <em>PN</em>.

So, tan 59^\circ = \frac{OP}{PN}

\Rightarrow OP = PN \times tan59^\circ

Putting the values of <em>PN </em>and tan59^\circ.

OP = 1.66 \times 7.4\\\Rightarrow OP = 12.3 ft

Hence, the value of <em>OP </em>is 12.3\ feet.

Solve for n: -16 + 3n = -(8 +5n)
umka21 [38]

-16 + 3n = -(8 + 5n)

The - sign outside the parentheses acts as a -1, and so it is distributed to each term in the parentheses.

-16 + 3n = -8 - 5n

+16

3n = 8 - 5n

+5n

8n = 8

/8

n = 1

the length of a rectangle is 5 inches more than the width the perimeter is 70 inches what is the length
nadezda [96]

The sum of length and width is half the perimeter, so is (70 in)/2 = 35 in. Since this is the sum of length and width, if we add 5 inches, it will be twice the length. That is ...

... length + width = 35 in

... length + (width + 5 in) = (35 in) + (5 in)

... 2×length = (35 in) + (5 in) = 40 in


The length of the rectangle is 20 inches.
