Besides the 90degree angle measure, what are the other two angle measures of a right triangle with side lengths 5, 12, and 13? R
Snezhnost [94]

Answer:

The other two angle measures are 23 degrees and 67 degrees

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

m\angle A+m\angle C=90^o ----> by complementary angles

sin(C)=\frac{AB}{AC} ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

sin(C)=\frac{5}{13}

C=sin^{-1} (\frac{5}{13})=23^o

Find the measure of angle A

m\angle A+23^o=90^o\\m\angle A=67^o

therefore

The other two angle measures are 23 degrees and 67 degrees

Anuta_ua [19.1K]

Answer:

It's 16m

Step-by-step explanation:

Let's say the missing side is C, and since the triangle is right-angle triangle, you can use Pythagoras theorem. Which is

C squared is equal to A squared plus B squared

Like this: c^2 = a^2+b^2

Then

c^2= (10)^2 + (12)^2

c^2= 100 + 144

c^2= 244

c=

\sqrt{244}

c = 15.6

Hope this helps :)
