Answer:
3.5
Step-by-step explanation:
Answer:70
Step-by-step explanation:
step 1:add up the angles you know
step 2:subtract the answer (220) from the total angle measure of a square which is 360 then you get 140
step 3: divide 140 by 2 because the two angles on the sides are equivalent and you get 70
As the two ratios, 6/4, and 10/6 are not equal, they are not in proportion.
<h3>What is Ratio?</h3>
When a number is divisible by another number, then it can be written in the form p:q, this is called a ratio and when two ratios are equal to one another then they are said to be in proportion.
In simple terms, the ratio is the comparison of two quantitites and proportion is the equality of two ratios.
The ratios are 6/4, and 10/6.
The first ratio is 6/4
The second ratio is 10/6
If the ratios are in proportion, they must be equal.
6/4
= 3/2
= 1.5
10/6
= 5/3
= 1.667
The two ratios are not equal.
So, if the two ratios are not equal, the two ratios are not in proportion.

<h3>
Answer: 20</h3>
Explanation:
For any rectangle, the diagonals are the same length.
AC = BD
7x-35 = 3x+45
7x-3x = 45+35
4x = 80
x = 80/4
x = 20
