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

y = x + 95

y = 42 + 95

y=137 mm hg
