Answer:

b = 5.65

Step-by-step explanation:

Since it's a right triangle, we can apply the Pythagorean theorem.

We know that the hypotenuse is 9, and one leg is 7. We are missing the other leg which is called b.

The Pythagorean theorem tells us that if the hypotenuse is c and the legs of the right triangle are a and b, then we have c^{2} = a^{2} +b^{2}

So we're going to solve this formula for the values given c= 9 and a = 7

9^{2} =7^{2} +b^{2} \\81=49+b^{2} \\81-49=b^{2} \\32=b^{2} \\\sqrt{32} =b

Thus, b = \sqrt{32} =5.65

Apply the Pythagoras Theorem

{c }^{2}  =  {a}^{2}  +  {b}^{2}
{9 }^{2}  =  {7}^{2}  +  {b}^{2}
81 =  49+  {b}^{2}
81  -  49 = {b}^{2}
32= {b}^{2}
Take square root of both sides

b =  \sqrt{32}
b = 4  \sqrt{2}

Given:

Two similar rectangles.

To find:

The area of the larger rectangle.

Solution:

Let x be the other side of the larger rectangle.

Corresponding sides of similar figures are always congruent.

\dfrac{x}{1}=\dfrac{4}{2}

x=2

The other side of larger rectangle is 2 cm.

We know that, area of rectangle is

Area=Length\times Width

So, area of the larger rectangle is

Area=4\times 2

Area=8

Therefore, the area of the larger rectangle is 8 sq. cm.

38. For the following exercises, sketch a line with the given features.
zhannawk [14.2K]

Answer:

see image

Step-by-step explanation:

The x-intercept is the point where the line crosses the x-axis (horizontal, left and right line with numbers, arrows at both ends, usually marked x at the right end)

The y-intercept is where your line crosses the y-axis (vertical, up-and-down line with numbers, arrows at the ends, usually marked y at the top)

Two points determine a line.

Draw a line through the two points given. See image.
