Answer:
m∠QRS = 52°
Step-by-step explanation:
From the given figure,
In right triangles ΔRQT and ΔRST,
QT = TS = 7.5 units [Given]
RT ≅ RT [Reflexive property]
ΔRQT ≅ ΔRST [By HL theorem of congruence]
Therefore, m(∠QRT) = m(∠SRT) = 26° [CPCTC]
m(∠QRS) = 2m(∠QRT)
= 2×(26°)
= 52°
Answer:
The Subjects: The subject of this research are the drivers who were selected randomly to take part in the experiment
The Treatment: The treatment for this research will therefore be driving and also talking on a cell phone at the same time and also driving while not talking on the phone
The response variable for the experiment: The number of errors that will be made by the drivers as they drive on an obstacle course.
Step-by-step explanation:
Answer:
D) 
, 
Step-by-step explanation:
The blue boundary line has a y-intercept of 2 and a slope of 2.
It has equation : 
Since the boundary line is not solid and the lower half plane of this line is shaded, its inequality is
The blue boundary line passes through the origin and has slope 
.
Its equation is 
Since the boundary line is not solid and the right half-plane is shaded, its inequality is
The correct choice is D.
Because the two angles equal each other:
80=20x and solve for x
These are corresponding angles
