Answer:
A. 7.5
B. 10
Step-by-step explanation:
The first one is 3x2 + half of 3x1 for 6 + 0.5*3 total.
The second one is 3x2 + 4 times half a 2x1 for 6 + 4 * 0.5 * 2 = 10
Answer:
The point of intersection of angle bisectors of the 3 angles of triangle ABC is the incenter (denoted by I). The incircle (whose center is I) touches each side of the triangle.
He is incorrect because 0.9 is equal to 0.90 which is greater than 0.74 because 9 is greater than 7
15 pieces will there be.
<h3> How many pieces will there be?</h3>
.5 is the same as 1/2, while 7.5 is the same as 7 1/2. To determine how many strips may be cut, use the following expression:
.5x = 7.5
This is due to the fact that the ribbon length that has to be cut is .5 feet, and we are attempting to determine how many pieces of that length might be cut from a roll of ribbon that is 7.5 feet long.
Divide both sides by 2.5 to separate the variable, and that's all there is to it.
7.5/.5 is 15.
x = 15.
Eli is able to slice a ribbon into three pieces that are each .5 feet long.
The complete question is: The red strips that are 1/2 feet long. The roll of ribbon is 7 1/2 feet long. Which expression could be one of the steps in determining how many strips can be cut?

For First Question:
As, we find the value of x for parallel condition of line a and b
so, m∠3 = m∠1 and m∠2 = 180°-m∠1 = 180°-(2x+15)° [ As straight line contain total 180°]
Now,
m∠2 = <span>m∠6 [ Because they are corresponding angles]
180</span>-(2x+15)=(3x+10)
180=3x+10+2x+15
x= 31 satisfies the condition of a||b
For second Question:
As, it is issoceles triangle So side AC = side BC So, m∠A=<span>m∠B
</span>4x+5=5x-1
x=6
So,
m∠A=29° and triangle contain total 180°
<span>m∠C=180-29-29
</span> =122°
Option D is correct
