Answer:
The answer to your question is: 30°
Step-by-step explanation:
Data
m∠ 1 = 5x
m∠ 3 = x - 24
Process
m ∠ 1 = m ∠ 3 because they are vertical angles
5x = x - 24
5x - x = 24
4x = 24
x = 24 / 4
x = 6
Angle 1 = 5(6)
= 30°
A relationship is proportional if they represent the same kind of relationship.
One way to tell if it is proportioned is to write them as fractions and then reduce them. If the reduced fractions are the same, the relationship is proportional.
Given : 2D + 1L = 100,
And D + L = 70
This is a simultaneous equation can be solved as follows
2D + L = 100
- D - L = -70
————————————-
D - 0 = 30
i.e D (number of dudes) = 30
Therefore, since we already know the fraternity sold 70 tickets in total,
70 -30 = 40 (the number of ladies attended)
Answer:
m∠T = 45
Step-by-step explanation:
RST and LMN are equal triangles, so the angles can be interchanged between the two.
That means R = 65, S = 70, and T = 180 - (70 + 65)
180 - (135)
45
