I can’t see the numbers but here is a way to help you solve. Domain go from left to right and range bottom to the top
Answer:
For x
We use cosine
cos 45° = 2/x
After solving
x = 2√2
Since we have the value of x we use it to get the value of y
we use cosine
cos 60° = 2√2/y
y =2√2/cos 60
y = 4√2
We use Pythagoras theorem to find z
(4√2)² = (2√2)² + z²
z² = 32 - 8
z² = 24
z = √24
z = 2√6
Therefore x = 2√2
y = 4√2
z = 2√6
Hope this helps.
The question is incomplete, the complete question is as follows:
What do Steven Hawking and Thomas Edison have in common
- Both men made mathematics discoveries
- Both men made discoveries that were well-received
- both men created technological inventions
- Both men used observations in their field of study
Answer:
- Both men made discoveries that were well-received
Step-by-step explanation:
Stephen Hawking and Thomas Edison were two great physicist or scientists, whose discoveries were well-recieved by all over the world.
Stephen Hawking gave theories in cosmology such as black holes that includes the second law, that states that black hole will never reduce its shape.
Thomas Edison was one of the great inventors in the history in different feilds such as mass communication, electric power generation, motion pictures, and sound recording. some of the inventions include Automatic Telegraph and tin foil phonograph.
They both have given scientific research and logics for their discoveries and so people accepted them.
Hence, the correct answer is " Both men made discoveries that were well-received
".
Answer: a = -3
Step-by-step explanation: First we distribute the -2 to a and -3 to get -2a+6=12, then subtract 6 on both sides, -2a=6, finally divide by -2 on each side to get a = -3.

He made $120.
You divide 1,320 by 22. That gives you 60. Then you times 60 by 2(which equals 120) because 60 represents the packets and he made 2 dollars per packet.
Mathematically the steps look like this:
1,320/22
=60
60(2) or 60 x 2
= 120
so $120
hope this helped!
