The number of the blue cubes is 35 and the number of the red cubes is 20.
<h3>What is the ratio?</h3>
The ratio is defined as the representation of the one number with respect to the other number. or one number is how many times the other number.
Given that:-
- In a bag, there are red and blue cubes in the ratio of 4: 7
- I add 10 more red cubes to the bag. Now there are red and blue cubes in the ratio of 6: 7
The number of the blue cubes are calculated as:-
The two equations will be formed by the given data in the question.
7r = 4b
7r + 70 = 6b
Solving the above equation we will get the value of b.
4b + 70 = 6b
6b - 4b = 70
2b = 70
b = 35
7r = 4b
7r = 4 x 35
r = 20
Therefore the number of the blue cubes is 35 and the number of the red cubes is 20.

A triangle has three angles, and their measures add up to 180 degrees.
An isosceles triangle has at least 2 congruent sides, and the angles opposite the congruent sides are congruent.
This triangle has one angle of 40 deg, and two angles that measure the same; call the measure of each base angle x.
x + x + 40 = 180
2x + 40 = 180
2x = 140
x = 70
The base angles measure 70 deg.
It must flip the image. (Not sure if this is the answer you're looking for though lol)
