Please help me! I am stuck please please! :(

side AC =  , angle A=30 degree   , angle B=60 degree

Step-by-step explanation:

using pythagors theorem

a^2 + b^2 =c^2

here a and b are the legs of the triangle whereas c is hypotenuse so,

10^2 + AC^2 = 20^2

100 + AC^2 = 400

AC^2 =400-100

AC^2 =300

AC=

AC=

For angle A

take angle A as reference angle

using sin rule

sin A =opposite/hypotenuse

sin A=

sin A=

A=

A=30 degree

For angle B

angle A + angle B + angle C =180 degree (sum of interior angles of a triangle)

30 + angle B + 90=180

120 + angle B =180

angle B =180-120

angle B =60 degree

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

the answer is 62.8 cubic units
