Question 1: The indicated angle is 30°
Question 2: The indicated angle is 44°
Question 3: The indicated angle is 39°
Question 4: The indicated angle is 18°
Question 5: The indicated angle is 37°
Question 6: The indicated angle is 17°
Step-by-step explanation:
As all the triangles are right-angled triangle, trigonometric ratios can be used to find the indicated angles.
Let x be the angle
<u>Question 1:</u>
The according to the angle
P = 22
B = 38
Tangent ratio uses both base and perpendicular so,
The indicated angle is 30°
<u>Question 2:</u>
According to the angle,
P = 28
B = 29
Again we will use tangent
The indicated angle is 44°
<u>Question 3:</u>
According to angle,
P = 22
H = 35
The indicated angle is 39°
<u>Question 4:</u>
According to angle,
B = 3
H = 9
We will use cos
The indicated angle is 18°
<u>Question 5:</u>
According to indicated angle,
B =35
H =46
The indicated angle is 37°
<u>Question 6:</u>
According to angle,
P = 15
H = 49
The indicated angle is 17°
