Which side lengths form a right triangle? Choose all answers that apply:

kkurt [141]

Answer:

All 3 are right triangles.

Step-by-step explanation:

In a right triangle c^2 = a^2 + b^2 where c is the longest side. ( by Pythagoras).

a) 3^2 = 9, 6^2 = 36 and √27 ^ 2 = 27

36 = 9 + 27

So this is a right triangle.

17^2 = 289, 15^2 = 225 and 8^2 = 64

289 = 225 + 64

Also right triangle.

c) √50 ^ 2 = 50, 5^2 = 25 and 5^2 = 25

So also right triangle.

Solve question 13. And 14. Please!! Will reward brainliest!!

SIZIF [17.4K]

Answer:

y = 4 sin( 0.5t - $\frac{4\pi }{3}$ ) - 2

y = a sin ( 2t - $\frac{-\pi }{3}$ ) + 2

Step-by-step explanation:

In the first question,

amplitude = 4

Period = $4\pi$

phase shift = $\frac{-4\pi }{3}$

Vertical shift = -2

Angular velocity , w = $\frac{2\pi }{time period}$

Here, w = $\frac{2\pi }{4\pi }$ = 0.5

The general equation of a wave is

y = a sin( wt + ∅ )

Putting above values in the equation,

y = 4 sin( 0.5t - $\frac{4\pi }{3}$ ) - 2

In the second question,

Amplitude is not given so we will take it as a.

time period = $\pi$

w = 2

Phase shift = $\frac{-\pi }{3}$

Vertical shift = 2

The equation is

y = a sin ( 2t - $\frac{-\pi }{3}$ ) + 2
