How do you solve 37.35= 15/x
Serjik [45]

Answer:

see below

Step-by-step explanation:

multiply both sides by x

37.35 = \frac{15}{x}

x * 37.35 = \frac{15}{x} *x

the x on the right side cancel out

37.35x = 15

now divide both sides by 37.35

\frac{37.35x}{37.35} = \frac{15}{37.35}

x = \frac{15}{37.35}

x ≈ 0.402

Let sin ? = 4/5, and cos ? = ?3/5, and find the indicated value
Charra [1.4K]
Let the unknown angle be x.
That is
sin x = 4/5
cos x = 3/5

By drawing a right triangle in the first quadrant,
hypotenuse = 5
Adjacent side = 3
opposite side = 4

That is tan x  = 4/3
From the calculator,
x = arctan(4/3) = 53 deg (nearest integer)

Answer: 53 deg. (nearest integer)
