The triangle has side lengths 10cm, 24cm, and 28cm, is it a right triangle? Explain please i dont understand
Nitella [24]

In every right triangle, if you add up the squares of the two
shorter sides, you get the square of the longest side. If you
don't then it's not a right triangle.

10² = 100
24² = 576

100 + 576 = 676

676 is the square of 26. 
It's NOT the square of 28.

So 10 - 24 - 28 is not a right triangle.

Those 2 questions I need help with . find sec θ and tanθ
Zielflug [23.3K]

STEP - BY - STEP EXPLANATION

What to find?

The the value of secθ.

Given:

(4, 3)

⇒(x, y) = (4, 3)

Step 1

Draw a sketch.

Step 2

Substitute the values into the trig. ratio formula below.

tan\theta=\frac{opposite}{adjacent}

From the sketch above, opposite = 3 and adjacent = 4

tan\theta=\frac{3}{4}

Step 3

Find the value of the hypotenuse side using Pythagoras theorem.

let h be the hypotenuse side.

\begin{gathered} h^2=4^2+3^2 \\  \\ =16+9 \\  \\ =25 \\  \\ h=5 \end{gathered}

Hence, hypotenuse = 5

Step 4

Substitute the values into the formula below:

\begin{gathered} cos\theta=\frac{adjacent}{hypotenuse} \\  \\ =\frac{4}{5} \end{gathered}

But,

sec\theta=\frac{1}{cos\theta}=\frac{1}{\frac{4}{5}}=\frac{5}{4}

ANSWER

secθ= 5/4

tanθ=3/4
