When the sum of two angles measures up to 90° then these angles are known as complementary angles of each other. The measure of ∠1 is 30°, while the measure of ∠2 is 60°.
<h3>What are Complementary Angles?</h3>
When the sum of two angles measures up to 90° then these angles are known as complementary angles of each other.
for example, ∠x + ∠y = 90°, therefore, the ∠x and ∠y are the complementary angles of each other.
Since the two angles together form a 90° angle. The angles are complementary to each other, therefore, we can write,
∠1 + ∠2 = 90°
x + x + 30 = 90°
2x = 60°
x = 30°
Thus, the measure of the angles can be written as,
∠1 = x = 30°
∠2 = x+30° = 60°
Hence, the measure of ∠1 is 30°, while the measure of ∠2 is 60°.

Yes that is correct good job
Answer:
Step-by-step explanation:
In this case we have a right angled triangle because 25^2 = 15^2 + 20^2 so its a right-angled triangle with the 2 legs = 15 and 20.
Area = 1/2 * 15 * 20
= 150
To find the slope you rise before you run and if you can't rise then you go downwards so it would be down -3 over positive 2
