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.
<span>If a ray lays in a plane, assuming it is contained by the plane, this results in a line intersection plane-line relationship. This means all the points of the ray are also in the plane.</span>
Answer:
7b - 7
Step-by-step explanation:
You can use distributive property which is x (a + b) = x*a + x*b and x (a - b) = x*a - x*b. Therefore, the expression is 2*b + 2*4 + 5*b - 5*3 which is:
2b + 8 + 5b - 15, which is, if you combine like terms:
7b - 7
First divide the new amount (7.28) by the original amount (7) and then times by 100
7.28 / 7 x 100 = 104
This tells us that 7.28 is 104% of 7
Minus this by 100 to get the sales tax rate:
104 - 100 = 4%
You could also subtract 7.28 by 7 first, then divide that by 7 and then multiply by 100:
7.28 - 7 = 0.28
0.28 / 7 x 100 = 4%
