Answer:

A = 77.32

Step-by-step explanation:

sin theta = opp/ hypotenuse

sin A = 80/82

sin A = 40/41

Take the inverse sin of each side

A = sin ^-1 (40/41)

A =77.31961651

To the nearest hundredth

A = 77.32

Usimov [2.4K]

From this picture you can calculate coordinates of triangles' vertices:
$A(-9,0),\ B(-6,-4),\ C(-3,0),\ J(8,0),\ G(5,4),\ H(2,0)$ .

Since

$\frac{-9+8}{2} = \frac{-6+5}{2}= \frac{-3+2}{2}=- \frac{1}{2}$ $\frac{0+0}{2}= \frac{-4+4}{2} = \frac{0+0}{2} =0$

you can conclude that points A, B, C are rotated by $180^0$ about the point (-0.5,0) to form points J, G, H, respectively.

Answer: A is correct choice.

10/7=x/5 proportion

LUCKY_DIMON [66]

$\boxed{\boxed{\text{ if } \dfrac{a}{b}=\dfrac{c}{d} \text{ then }a\times d=b\times c}}$

$\dfrac{10}{7}=\dfrac{x}{5}\\\\10\times5=7\times x\\50=7x\\7x=50\\\\\boxed{x=\dfrac{50}{7}}$
