We can first solve for the face diagonal. That is $\sqrt{(10^2+5^2)}$ . Notice this will form a right triangle with the vertical side. We get that the face diagonal = $\sqrt{125}$ . Now, we can use Pythagorean theorem again to get the straw length:

$s^2 = 9^2+\sqrt{125}^2$ where s = the straw length.

We can solve that s = $\sqrt{206}$

What is the image of C for a 90 degree counterclockwise rotation about A?

Mashcka [7]

counter clockwise would be rotating it up to the right.

C is 4 spaces away from A ,

A is on X3 & Y3 so 4 +3 = 7

so it would be x7 & Y3 so (7,3), the first answer

Triangle ABC is an oblique triangle. If angle A equals 57°, angle B equals 73°, and AB equals 24 in, what is the length of AC?

natulia [17]

Step-by-step explanation:

$\huge{\underbrace{\overbrace{\mathfrak{\pink{Answer:}}}}}$

Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°

And using rhw Law if Sines, we have.....

AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in
