Answer:
12
Step-by-step explanation:
1) to calculate the length of RT (in ΔRST):
SR/sin60°=12√3 / (√3/2)=12.
2) in ΔQRT RT=RQ=x (the m∠T=m∠Q !), then x=12.

i will only tell you the answer only if u give me the brinlest
Step-by-step explanation:
Answer:
1) x = 60° ; y = 70°
2) x = 50° ; y = 80°
3) x =110° ; y = 60°
4) x =60° ; y = 90°
Step-by-step explanation:
1)
We have to find the interior angle y
= 180 - 120
= 60°
Now we have to find x
=180 - (60 + 50)
= 180 - 110
= 70°
2)
We know that opposite angles are equal
So therfore y = 80°
x = 180 - 80 + 50
x = 180 - 130
x = 50°
3)
According to the figure we see that x+y=180
Exterior angle = sum of two interior angle
So, x = 50 + 60
x = 110°
Now we substitute in the x value
x + y = 180
110 + y = 180
y = 180 - 110
y = 70°
4)
Opposite angles are equal
x = 60°
The figure is a right angle triangle
So,
y =90°
Answer:
Since angles 1 and 3 are Congruent, it means they are same.......1
Now 1 and 2 are supplementary since they are a linear pair.........2
Substituting 3 for 1 in (2) implies Angles 3 and 2 are also Supplementary
C is the Answer

Answer:
Charley's class.
Step-by-step explanation:
There are 25 students in Amanda class and 27 in Charley's.
Number of students with no pets in Amanda's = 7 which is 100 * 7/25 = 28%.
In Charley's class this is 8 which is 100 * 8/27 = 29.6%.
