Answer:
The answer is 45.
Step-by-step explanation:
60% of a number is 54, find the original number
54 ÷ 60%
= 54 ÷ 60/100
= 54 * 100/60
= 90
50% of 90 is
90 * 50%
= 90 * 50/100
= 90 * 1/2
= 45
Construct two angle bisectors of the triangle
Answer:
Option (D) is correct
<u>Step-by-step explanation:</u>
We have to contruct two angle bisectors of the triangle.
various steps to inscribe the circle in a triangle are
- First draw a triangle
- Draw angle bisector of one angle
- Draw angle bisector of another angle
- Extent these angle bisectors, where they meet that point will be called the incenter
- From incenter draw prependicular to any side of the triangle
- The length from the point where the prependicular touches the side of triangle to the point of incenter will be radius.
- Use this radius and draw the incircle.
You have to use PEMDAS, it stands for parenthesis, exponents, multiplication, division, addition, and subtraction. So first you have to subtract the numbers in the parenthesis which is -3.5 (9/18=1/2). Since there are no exponents or multiplying or dividing, we skip those. Now, we do 5-1/3 and we get 4 2/3. Lastly, add 4 2/3 and -3.5(which is equal to -3 1/2). We get 2 1/6=13/6=1.166666667
