Answer:

exterior angles:

144°and 36°

126° and 54°

90° and 90°

Step-by-step explanation:

we know that each angle in a triangle adds up to 180°.

so,

2x+3x+5x=180

10x=180

x=180/10

x=18

the interior angles are:

2x=36°

3x=54°

5x=90°

and explanation is provided to find the exterior angles above.(sorry for the bad handwriting)

Answer:

$\approx 0.59\text{ ft by }0.91\text{ ft}$

Step-by-step explanation:

Let $\ell$ represent the length of the rectangle. The width can be represented as $0.64\ell$ .

The perimeter of a rectangle with lengths $l$ and $w$ is given by $p=2l+2w$ .

Thus, we have:

$2\ell+2(0.64\ell)=3,\\2\ell +1.28\ell=3,\\3.28\ell=3,\\\ell=0.91463414634\approx 0.91$

The width is then $0.64(0.91463414634)=0.58536585365\approx 0.59$ .

Answer:

2. quadrant 4

3. quadrant 2

4. quadrant 3

Step-by-step explanation:

You can refer to the picture.

2. Since $tan\theta$ less than 0 which means $tan\theta$ is negative, $sin\theta$ less than 0 which means $sin\theta$ is negative.

So, the angle lies in quadrant 4 (Cos quadrant)

3. Since $tan\theta$ less than 0 which means $tan\theta$ is negative, $cos\theta$ less than 0 which means $cos\theta$ is negative.

So, the angle lies in quadrant 2 (Sin quadrant)

4. Since $tan\theta$ more than 0 which means $tan\theta$ is positive, $sin\theta$ less than 0 which means $sin\theta$ is negative.

So, the angle lies in quadrant 3 (tan quadrant)

pickupchik [31]

Answer:

412.7 square feet

Step-by-step explanation:

A circle of circumference 72 ft will have a radius given by ...

C = 2πr

(72 ft) = 2(3.14)r

r = (72 ft)/(6.28) ≈ 11.465 ft

The area of a circle with that radius is ...

A = πr² = 3.14(11.465 ft)² ≈ 412.7 ft²

Sirgeo can enclose a circular area of about 412.7 square feet with 72 feet of fence.
