Find the measure of the missing angle.
1 answer:
Answer:
The answer is
<h2>49.5°</h2>Step-by-step explanation:
Let the angle be x
Since the triangle is a right angled triangle we can use trigonometric ratios to find the value of x
To find the value of x we use cosine
From the question
the adjacent is 13
the hypotenuse is 20
The angle is
We have the final answer as
<h3>49.5°</h3>Hope this helps you

Answer:
B. 10
Step-by-step explanation:
First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)
Let's first label the leg of the second triangle as y.
Then, we can set up this equation
Cross multiplying gives us
84=y^2
So, y=sqrt(84) or 2 sqrt(21).
Now, using the pythagorean theorem, we get
4^2+2sqrt(21)^2=x^2
100=x^2
x=10
