Please help me tysm i dont understand

h = 2

b = 3

Step-by-step explanation:

to find 'h' we can use the ratio of sides in a 30-60-90° triangle which, respectively, is 1 : : 2

so we can set up this proportion:

h/2 = 1/

cross-multiply:

h = 2

to find 'b' we can use the ratio of sides in a 45-45-90° triangle which, respectively, is 1 : 1 :

we can set up this proportion:

3/b = 1/

cross-multiply:

b = 3

sinθ is equal to the division of the opposite side of the reference angle (θ) by the hypotenuse.

the cosine of an angle in a right triangle equals the adjacent side divided by the hypotenuse

tan30 = h/2

1/sqrt3 = h/2

sin45 = 3/b

1/sqrt2 = 3/b

b/sqrt2 =3

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
