Answer:
43 degrees
Step-by-step explanation:
every triangle all three angles equal 180 for a right triangle you know that one angle is 90 degrees for this triangle we know that another angle is 47 so
90+47 = 137 now we can take 180 - 137 = 43
so your third angle is 43
hope I helped!!

Hi, I’m Lena and I’ll be here to answer your question with a good-quality answer. If there's something I can improve, let me know! ツ
♡ Let’s look at the main important things that will lead you in the correct path.
♥ <em>a </em>+<em> b</em> usually = <em>c!</em> Unless the book asks you to find a specific variable, you will most likely be looking for <em>c</em>.
♥ <em>A</em> = <em>bh</em>/2! This is the formula for the area of a triangle. You can also read this as A = base * height/2. The good thing about this formula is you don't need a picture. You can write it as <em>a</em> * b<em> </em>or <em>b</em> * <em>a!</em>

♡ Now, let's solve!
♥ Plug the numbers into the formula: 5*8/2.
♥ Solve! In this case, we do not need c: 40/2 = 20.
Your answer should be 20! Please do not hesitate to ask me any questions.
Equation for slope.
y2 - y1/x2 - x1
Using (x,3) and (5,9)
9 - 3/5 - x = 2
6/(5 - x) = 2
Cross multiply
6 = 2(5 - x)
6 = 10 - 2x
6 - 10 = -2x
-4 = -2x
x = 2
y2 - y1/x2 - x1
9 - 3/5 - 2
6/3 = 2
Hope this helps.
