27%
65/245 = 0.2653
Multiply 0.2653 by 100 to get the percentage = 26.53%
Rounding to the nearest whole percent = 27%
Answer:
x=-8
Step-by-step explanation:
y=8 is a horizontal line crossing the y-axis at 8
A line perpendicular to this would be a vertical line crossing the x-axis at -8
Answer:
24) x = 9.2
25) x = 30.8
Step-by-step explanation:
Given
See attachment for triangles
Solving (24)
To solve for x, we make use of cosine formula
i.e.
cos(40) = adjacent ÷ hypotenuse
So, we have:
cos(40) = x ÷ 12
Multiply both sides by 12
12 cos(40) = x
12 * 0.7660 = x
x = 9.2
Solving (25)
To solve for x, we make use of sine formula
i.e.
sin(25) = opposite ÷ hypotenuse
So, we have:
sin(25) = 13 ÷ x
Multiply both sides by
x sin(25) = 13
Divide by sin(25)
x = 13 ÷ sin(25)
Using a calculator
x = 30.8
Answer:
y <7
Step-by-step explanation:
15-y>8
Subtract 15 from each side
15-15-y>8-15
-y>-7
Multiply each side by -1, remembering to flip the inequality
-1 * -y > -7*-7
y <7
Here's 2 (almost) equations:
m<1 = m<3
m<1 + m<2 + m<2 + m<3 = 360
I got the first one because angle 1 and 3 are on opposite sides, so they must be equal. I got the second one because 2 and (unlisted) 4 must be equal, and all of the angles added must be 360.
