Answer:

64 feet squared

Step-by-step explanation:

Since it's a square, all sides have a length of 8 ft. Area is length x width, so simply multiply 8 by itself. 64 feet squared is therefore the answer.

If <PQR and <RQS form a linear pair, they are supplementary or add up to 180. So, (5x+5) + (11x-65) = 180 ... Combining like terms, it would be : 16x-60=180. 16x=240, x=15. They've asked for the measure of <PQR, so substitute it in! 5x+5= 5(15) +5= 80.

Happy Solving!

9. What formula could be used to find the area of the image?

Scilla [17]

Answer:

9. Area of triangle= $\frac{1}{2} \times base\times height$

10. Base= 16 ft and Height= 15 ft.

11. 120 ft²

Step-by-step explanation:

Given: Base of triangle= 16 ft

Length of leg of triangle= 17 ft.

As shown in the picture that median has bisected the triangle and forming two right angle triangle.

∴ Each base of right angle triangle= $\frac{16}{2} = 8\ feet$

Now, finding the height of triangle by using pythagorean theorem.

We know, $h^{2} = a^{2} +b^{2}$ , where h is hypotenous, a is height or opposite and b is base or adjacent of triangle.

⇒ $17^{2}= a^{2} + 8^{2}$

⇒ $289= a^{2} + 64$

Subtracting both side by 64

⇒ $225= a^{2}$

taking square root on both side, remember; √a²=a

⇒a= $\sqrt{225} = 15$

Hence, height of triangle is 15 ft.

Next, finding the area of triangle.

Formula; Area of triangle= $\frac{1}{2} \times base\times height$

⇒ Area of triangle= $\frac{1}{2} \times 16\times 15$

∴ Area of triangle= 120 ft²
