What is the value of x, rounded to the nearest degree?

71

Step-by-step explanation:

You us SOH CAH TOA

In this case you use SOH also called cosine.

This means cos(x)=adjacent/hypotnuse

Now you plug in the numbers

cos(x)=4/12

You put this in your calculator and get

70.5287794

Which then can be rounded to

71 degrees

associative property hopes this ! : )

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
