4.That first one sounds familiar; I think I did it yesterday.
The sides don't matter (except that they're equal) so the base angle b satisfies
b + b + 38 = 180
2b = 142
b = 71
Choice a
5.
42 + 42 + v = 180
v = 180 - 84 = 96
choice d
6. That's three acute angles, an acute triangle
7. We need to satisfy the triangle inequality which means the sum of the two smaller sides needs to be bigger than the largest
10+15>24 so choice b
8.
SRT = RTS = 180 - STU
3x - 50 = 180 - 7x
10 x = 230
x = 23
choice a
Answer: 7 4/5
Step-by-step explanation:
When you subtract a negative number its the same as adding the number so youd be doing 7 1/5 + 3/5 and 1/5 + 3/5 is 4/5 and then you bring the 7 with it
The answer is 18 because 27 minus 18 is 9 and 9 is 2x less
The product of (5 sqrt 2-4 sqrt 3)(5 sqrt 2-4 sqrt 3) is
Step-by-step explanation:
We need to find product of (5 sqrt 2-4 sqrt 3)(5 sqrt 2-4 sqrt 3)
Writing in mathematical form
We can write it as:
Using square formula:
So, the product of (5 sqrt 2-4 sqrt 3)(5 sqrt 2-4 sqrt 3) is
