Answer:
m STW = 115°
Step-by-step explanation:
here, SU || VX
m STW = m UTR
( vertical opposite angles )
Hence, STW = 115°
Answer:
135 inches
Step-by-step explanation:
A scale factor is the size of the object on paper.
So to get the actual size we must multiply by the reciprocal of the scale factor.
Dividing by 1/20 is the same as multiplying by 20.
Since the scale is 6.75 (I converted 3/4 to 0.75), we must multiply by 20 to get our original height.
So 6.75 * 20 = 135 inches
Steps:
1. Graph all three points on the xy-plane.
2. Connect each point to form a triangle.
3. Use the formula A = (1/2)(base)(height)
Answer:
20
Step-by-step explanation:
i think hope it correct
Let the number be x.
First student increased the number by 23, therefore
⇒ x + 23
Second student decreased the number by 1, therefore
⇒ x - 1
The first student's result was 7 times greater than the result of the second student's, therefore
⇒ x + 23 = 7(x - 1)
----------------------------------------------
Solve for x:
----------------------------------------------
x + 23 = 7( x- 1)
x + 23 = 7x - 7
6x = 30
x = 5

Answer: The number on the board is 5.
