Which line segment is parallel to GE? DH KI FG HI

son4ous [18]

The right answer is KI

This is a square prism. The bases of this type of prism are squares. In square prisms the opposite sides and angles are congruent. In this problem, we need to find which line segment is parallel to GE, so the right answer is KI as solved in the Figure bellow. Recall that parallel lines are lines that have the same distance apart called equidistant.

There are 180 degrees in a triangle

4. 38+38= 76 degrees

180-76=104

Isosceles, Obtuse

5. 65+ x+x=65

Well we know one of the x

It is 90 degrees because it is a right angle

65+90=155

180-155=25

Scalene, Right triangle

6. 71+45= 116

180-116=64

7. Scalene, acute

8. 126+22=148

180-148=32

Scalene, Obtuse

9. 50+90=140

180-140=40

Right angle, Scalene

The number p is 20 more than the number q . using algebra write the relationship between p and q .

Anarel [89]

From what we know, p is 20 more than q. So, we can assume p = 20 + q. Q can also be found by subtracting 20 from both sides. So, q = p - 20.

Hope this helped!

The last time Sierra played softball, she hit the ball 45% of the times she was at bat. Based on this information, how many time

Ymorist [56]

Answer:

Number of times she will hit the ball the next time she plays softball if she is at bat 20 times = 9 times

Step-by-step explanation:

Percentage of times Sierra hit the ball when she was at bat playing softball= 45%

So, we can find:

Number of times she will hit the ball the next time she plays softball if she is at bat 20 times = $\textrm{45\% of 20 times} =0.45\times 20=9\ times$
