The flag is an isosceles triangle. A flag is an isosceles triangle. The height of the flag is x. The angle opposite to x is 36 degrees. The side above the angle is 5 feet. The bottom side of the flag measures 5 feet because the triangle is . Because , the trigonometric triangle formula is used to calculate that the area is One-half(5)(5)sin(36°) ≈ 7.35 square feet. Recalling that this triangle is isosceles, we can write the area equation to solve for x. = One-half(x)(5)sin(). Solving for x and adding this value to the length of the other sides, the perimeter ≈ (rounded to the nearest tenth).

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

y=x+9

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
