Answer:
Step-by-step explanation:
The exterior angle is 151 degrees. The theorem states that the sum of its 2 remote interior angles, 5x+3 and 9x-20, will add up to this exterior angle. Therefore,
5x+3+9x-20 = 151 and
14x - 17 = 151 and
14x = 151 + 17
14x = 168 so
x = 12
If you want to find out the measure of each of these angles, just plug in 12 for x and do the math:
5(12) + 3 = 63 and
9(12) - 20 = 88 and
88 + 63 = 151 as it should.
were is the pictrue i dont see one maybe repost it
Give brainlest please i will do anything the answer is 48
0.08 is the answer to your question. If you have a calculator use it.
Answer:
Step-by-step explanation:
Focus on #7. Let's combine the first two matrices inside round parentheses.
We get
-2 - 1
4 + 3
and so the original problems becomes
-3 4
3( [ ] + [ ] )
7 2
Combining the two matrices, we get the following:
1 3
3([ ]) = [ ]
9 9
