So the right angle is equal to 90° and the rest is unknown.
using the triangle sim theorem, which states that all interior angles are equal to 180°.
so it would be x+2x+90°=180°.
then you would need to simply which is 3x+90°=180°
subtract 90° from both sides and get 3x=90°
and then divide both sides by 3 which is 30°
then you would need to find the angle of B which is 2x so you would need to substitute 30° for x which is 60°
the answer is 60°

Answer:
b. 8,800,000.
Step-by-step explanation:
In maria study the number of cars on the road increases by 10% each year.
Total number of cars in the first year =80 million cars.
We will add 10% of 80 million to 80 milion to enable us get the number of cars for the second year.
For year 2 we have;
10% of 80,000,000+80,000,000
8,000,000 + 80,000,000
88,000,000
number of cars in year 2 = 88 million
We will add 10% of 88 million to 88 milion to enable us get the number of cars for the third year.
8,800,000+88,000,000
96,800,000
the number of cars on the road in year 3 compared to year 2 will just be the increase which is in BOLD. That is 8,800,000
<em>or simply subtract the number of cars in year 2 from that in year 3;</em>
96,800,000-88,000,000 = 8,800,000
