M∠ rst + m∠ vst = 180°
3 x + 7° + 9 x + 17° = 180°
12 x + 24° = 180°
12 x = 180° - 24°
12 x = 156°
x = 156°: 12
x = 13°
m ∠ rst = 3 · 13° + 7° = 39° + 7° = 46°
m ∠ vst = 180° - 46° = 134°
Answer:
A ) 46° and 134°
Answer:
1. Calculate the sum of "a", "b" and "c".
2. The perimeter equation is: 
Step-by-step explanation:
In this case, P denotes the triangle's perimeter while a, b, and c are the triangle's sides.
The definition states that the sum results from an addition operation. Thus, the statement "The perimeter P of a triangle equals the total of sides a, b, and c" means that the perimeter is determined by aggregating the lengths of the triangle's sides.
Consequently, you can express this in the following equation:

Answer:
0.40 feet
Step-by-step explanation:
For the first scenario, a 50-foot building casts a shadow of 1 foot. Let the angle of elevation of the sun from the shadow be denoted as θ.
Then:
Tan θ = 
Tan θ = 
Tan θ = 50
⇒ θ =
50
= 88.8542
= 
The elevation angle is roughly
.
For a 20-foot pole,
Tan θ = 
Tan
= 
x = 
= 0.4015
= 0.40 feet
The length of the pole's shadow is 0.40 feet.
The complete question reads:
Peter created two rays, AC and AP, sharing a common vertex at point A. Which of the following statements
might accurately describe Peter's drawing?
I. AC and AP are parallel.
II. PAC represents an angle.
III. AC and AP are at right angles.
A. I and II
B. II and III
C. I and III
D. I, II, and III
Answer:
Option B: II & III
Step-by-step explanation:
We know Peter has drawn rays AC and AP.
Since the point A is shared as the endpoint, it indicates an angular relationship at this common point.
This angle could potentially be 90°, suggesting that rays AC and AP may be perpendicular.
Thus, the valid statements that characterize his drawing are: II & III.
BD=7x-10
Solution: x=bd/7 + 10/7
BC=4x-29
Solution: x=Bc/4 + 29/4
CD=5x - 9
Solution: x= cd/5 + 9/5
