<h2>20</h2>
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.

Answer:
See below.
Step-by-step explanation:
the one on the left area is 104
the one on the right area is 19.5
Answer:a=130,b=50
Step-by-step explanation:
a+b= 180
2a-5b=10
2(180-b)-5b=10 (I have substituted (180-b) for a here.)
360-2b-5b=10
350=7b
b=50
a+50=180
a=130
