The measure of the angles is given as 46°, 42°, and 92° respectively.
The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let the number be x,
According to the question,
1st angle = 7x + 4
2nd angle = 1 st angle - 4 = 7x
3rd angle = 2 [1st angle]
= 2[7x + 4] = 14x + 8
For a triangle, the sum of the angle should be 180°
7x + 4 + 7x + 14x + 8 = 180
28x + 12 = 180
28x = 168
x = 168 / 28
x = 6
Now,
1st angle = 7[6] + 4 = 46°
2 nd angle = 46 - 4 = 42
3rd angle = 2 × 46 = 92°
Thus, the measure of the angles is given as 46°, 42°, and 92° respectively.

In algebraic expression would I have an + sign or??
Answer:
100 /( 5 x 4 + 4³) = 1 4/21
100 / 5 x 4 + 4³ = 144
Step-by-step explanation:
100 /( 5 x 4 + 4³)
PEMDAS tells us to do what is inside the parenthses
We will do the power in side the parentheses first 4^3 = 64
100 /( 5 x 4 + 64)
Now we will multiply
100/(20+64)
Now we add inside the parentheses
100/84
Divide the top and bottom by 4
25/21
Changing from an improper fraction to a mixed number
1 4/21
OR
100 / 5 x 4 + 4³
If the quantity is not in parentheses
We will do the power first 4^3 = 64
100 / 5 x 4 + 64
Then we do the multiplication and division from left to right
20 *4+64
80+64
144
Answer:
144
Step-by-step explanation:
4 x 4 x 4 = 64
100/5 = 20
20 x 4= 80
80 + 64 =144
