Solve for x in the triangle. round to the nearest 10th.

X would be 96

Step-by-step explanation:

64 + 20 = 84

180 - 84 = 96

That's how you get the Answer

Let me know if this helps

x=7.8

Step-by-step explanation:

so first you figure out what the 20 and x are compared to the 64. the x is the adjacent angle and the 20 is the hypotenuse. so in this equation A and H are used making it a cosine equation. the equation would be set up cos64= x/20. then you would multiply the 20 and cos by 20 canceling out the 20 on the right side of the equation. then the equation would be 20cos64=x then in the scientific calculator you would type 20cos64 and that would give you 7.83 but when simplified it becomes x= 7.8

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
