Step-by-step explanation:
The right triangle has two sides 5 and 12 , by Pythagoras it's hypotenuse is 13.
Tan B=5/12,
Sin A =12/13
Answer:
16 degrees
Step-by-step explanation:
<u><em>The question is</em></u>
Find the measure of angle R
we know that
An exterior angle of a triangle is equal to the sum of the opposite interior angles
so
In this problem

we have

substitute


The answer is 9/7!! Hope it helps
When you have something to an exponent and the exponent is a fraction it basically means the numerator is the power of the number and denominator is the root of the number.
81^3= 531441
4 root (531441)=27
if you have a graphing or scientific calculator you should be able to enter straight in 81^(3/4).
