One ratio is 30:40 since 15 times 2 is 30 and 20 times 2 is 40.
4x-3.20yx
I’m other words this would be the same as a(b-c)=ab-ac
Answer:
The equation is;
(2x-2) + (4x + 2) = 180
x = 30
m∠A = 58
Step-by-step explanation:
Mathematically, when two angles are supplementary, the values of both angles add up to be 180
From
what we have here;
(2x -2) + (4x + 2) = 180
2x -2 + 4x + 2 = 180
6x = 180
x = 180/6
x = 30
Recall;
The measure of angle A is as follows;
2x -2 = 2(30) - 2 = 60-2 = 58
