<h3>
Answer: 140 degrees</h3>
==================================================
Explanation:
See the diagram below.
We start with triangle PQR with the given angles mentioned. Then you extend out segment QR to form line QR. It goes off infinitely in both directions.
The exterior angle x adds to the interior angle Q = 40 to get 180
x+40 = 180
x+40-40 = 180-40 ... subtract 40 from both sides
x = 140
The exterior angle is 140 degrees
Answer:
1) 19³=6859
2) 16² =256
3) 15³ =3375
4) 20² =400
5) 10³ =1000
Step-by-step explanation:
using your calculator to (square = number times itself) or (cube = number times itself times itself again)
If this is what u are asking for 240 is what i got for the answer
Hello!
<h3><em><u>Answer</u></em></h3><h3 />
The surface area of the cube is 150
.
<h3><em><u>Explanation</u></em></h3>
A = 6 ![a^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D)
A = 6 ![5^{2}](https://tex.z-dn.net/?f=5%5E%7B2%7D)
A = 6 × 25
A = 150
