To get 10 % you have to divide by 10 .
so 154.99 ÷ 10 = 15.499.
that's 10% but you want 20% so you times 10% by 2.
15.499 X 2 = 30.998.
154.99 - 30.998 = 123.992.
you then need to round the answer so you get $123.99
Hope this helps!!
Answer:
The angle measure for the bottom two angles in order for the triangle to be classified as an isosceles triangle are 30 degrees each
Explanation:
An isosceles triangle has two of its angles equal.
Given that one angle is 120 degrees, assuming the remaining angles are equal, since the sum of the angles in a triangle is 180 degrees, we have:
120 + x + x = 180
120 + 2x = 180
2x = 180 - 120 = 60
x = 60/2 = 30
Each of the remaining angles measure 30 degrees
Answer: 25
Step-by-step explanation:
You take 100/16 and get 6.25. Then you just multiply 4 by 6.25 to get 25
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 :)))
Answer:
108
Step-by-step explanation:
we first add 7+8=15 then 15×2=30 30+6=36 36×2=108
