Solve for an Angle in right triangles

Mathematics
1 answer:
Vedmedyk [2.9K]3 years ago
8 0

Answer:

B = 56.25

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adjacent/ hypotenuse

cos B = 5/9

Take the inverse cos of each side

cos ^-1 (cos B) = cos ^-1 (5/9)

B =56.2510114

To the nearest hundredth

B = 56.25

Are 165° and 1965° coterminal?​
MatroZZZ [7]

two angles are coterminal, namely land on the same spot on the circle.

let's check.

let's firstly divide 1965° by 360°, since 360° is a full circle, that way we know <u>how many full circles are</u> in 1965°.

1965 ÷ 360, gives us a quotient of 5 with some remainder.

5 * 360 = 1800, 5 full circles

if we subtract the full circles from 1965

1965 - 1800 = 165

low and behold, the remainder from that division is 165°  ✔

in other words, 1965°, goes around the circle 5 times and then lands 165° after all that, in the same spot as 165°.

Roman55 [17]

Answer:

W = (h-kn-1)/2

Step-by-step explanation:

h - 2W = kn +1

Subtract h from each side

h - 2W-h = kn +1-h

-2W  = kn +1-h

Divide each side by -2

-2W/-2 = (kn+1-h)/-2

W = (h-kn-1)/2
