9x+18=90
9x=72
x=8
This is the answer for problem 10 above
Problem 11:
62+58= 120
180-120 =60
Therefore angle FEA is 60 degrees
59+ 61=120
180-120= 60
Therefore angle CHF is also 60 degrees
Rays:
EB and HD ; EA and HC are both parallel because they have equivalent degree angles
Answer:
The correct answer is 25.
Step-by-step explanation:
A cooking magazine shows a photo of a main dish on the front cover of 5 out of the 12 issues it publishes each year.
Number of publications by the magazine every year = 12.
Number of publications in 5 years = 12 × 5 = 60.
Out of these 12 magazines in a year, the photo of a main dish is on 5 magazines.
Therefore in 60 magazines, the photo of a main dish would be 5 × 5 = 25 magazines.
Thus in five years there would be 25 publications in which the front page will have a poster of a main dish.
Answer:
Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.
Step-by-step explanation:
Triangular Proportionality Theorem states that:
- If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.
Let us consider the triangle ΔABC as shown in attached figure.
If
║
then
Therefore, Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.

Let the consecutive integers be x and x+1.
Then,
x + (x + 1) = 23
=> x + x + 1 = 23
=> 2x + 1 = 23
=> 2x = 23 - 1
=> 2x = 22
=> x = 22/2
=> x = 11
So, the integers are:
x = 11
and x + 1 = 11 + 1 = 12
So, the consecutive integers are 11 and 12.
