Please answer the question that is in the photo attached below

Step-by-step explanation:

In order to solve for this equation we have to note a couple of things.

There is a diagonal square inside a larger square. The space formed by the smaller square not being in the larger square is a right triangle.

The side length of the smaller square (4) is also the hypotenuse of this triangle.

Since we know that the other side length of the triangle is 3, we can use the Pythagorean Theorem to find the value of b.

The Pythagorean Theorem states that , where a and b are the legs and c is the hypotenuse.

We can substitute 3 in as a and 4 in as c and find b.

So b is units long.

Hope this helped!

Step-by-step explanation:

Use Pythagorean Theorem:

A² + B² = C²

3² + B² = 4²

9 + B² = 16

B² = 7

B = √7

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

the answer is a if my teacher taught me correct
