Answer:
C) 155
Step-by-step explanation:
all these angles add up to 360, so --
25 + 34 + 146 + m<9 = 360
205 + m<9 = 360
m<9 = 155, C)
Answer:
(1 , 27)
Step-by-step explanation:
The ordered pair (1 , 27) means:
x = 1
y = 27
Now putting value of x and y in given equation to check weather it satisfies:
y = 12x + 15.
27 = 12 (1) + 15
27 = 12 + 15
27 = 27
hence proved

Answer:

Step-by-step explanation:
The initial dimensions of the paper are:
(length)
(width)
After the paper is cut along the diagonal, we remain with a right triangle, of which the length and the width corresponds to the base and the height.
For a triangle, the area is calculated as

where
b is the base
h is the height
Here we have:

Therefore, the area of the triangle is:
