Answer:
Step-by-step explanation:
x+5+x+7x-5=180 degree (being the interior angles of a triangle)
9x=180
x=180/9
x=20 degree
76.91 = C
cos(77)= (17-3)/ C
Answer:
32
Step-by-step explanation:
2⊥ 96, 112, 176
2 48, 56, 88
2 24, 28, 44
2 12, 14, 22
2 6, 7, 11
Highest common factor= 2x2x2x2x2= 32
12 students/1 teacher = 276 students/x teachers
Students are on top of the ratio and teachers are on the bottom of the ratio. It must remain the same on both sides of the equation.
12 x = 276
divide by 12
x =23
Answer:
72 square inches.
Step-by-step explanation:
Convert feet and inches.
36 feet = 36*12 inches
=432 inches
Width of the floor; Converted from feet to inches:
32 feet = 32*12 inches
= 384 inches
Calculate how many times the length (l) has been scaled down.
432 inches of length has been reduced to 9 inches.

Now the length has been scaled down 48 times.
Scale down the width (w) 48 times.

The width of the scale drawing = 8 in
Area of the Scale drawing = Scaled down length * Scaled down width
