Step-by-step explanation:
It is an isosceles triangle , it has two equal angles both 55°.
All Isosceles triangles have two equal angles <em>a</em><em>n</em><em>d</em> two equal sides.
So in this case x +18 is equal to 3x, and to find x you will equal them to each other to create a linear equation and solve.
x + 18 = 3x
x - 3x = -18
-2x = -18
× = -18 / -2
× = 9 <em>(</em><em>a</em><em>n</em><em>s</em><em>)</em><em> </em>
Hope I was able to help. Good Luck :)))
All angles on a triangle add up to 180. If it's a right triangle it would be set up like this: 90+3x-4=6x-5=180. You would subtract 90 from 180 and get 90 left. 3x-4+6x-5=90. Then you would add 5 and 4 to 90.....3x+6x=99. Then you add 3x and 6x then you would be left with 9x=99. Divide 99 by 9 and you get x=11.
Answer:
A is true and B is false.
Step-by-step explanation:
x + 6.2 ≥ 10.9
Replace x for 4.7...
4.7 + 6.2 ≥ 10.9
10. ≥ 10.9 ( So this is true!)
x - 6.2 ≤ - 5
Replace x for 4.7...
4.7 - 6.2 ≤ -5
-1.2 is not ≤ -5 (So this is false!)
To solve:
Simplify 128x^5/8x first
16x^4
then divide by 1/4
16x^4•4/1=64x^4
Answer: 64x^4
