Answer:
i think its this one. 156.5cm
Step-by-step explanation:
To find this take note the scale is 1 cm:8 ft and the actual building is 1252 ft tall.
So we will divide 1252 by 8.
1252/8= 156.5
Let's convert the equation in point-slope form to slope-intercept form.
y - 4 = -(x - 6)
Multiply everything out.
y - 4 = -x + 6
Add 4 to both sides.
y = -x + 10
To be perpendicular, the slope of the new has to be the reciprocal of the other line. To slope in this equation is -1/1. To get the reciprocal, flip the numerator and denominator and change the sign too.
-1/1 becomes 1/-1, and changes to 1/+1, or 1.
y = x + b
Input the coordinate point and solve for b.
-2 = -2 + b
Add 2 to both sides.
0 = b
y = x
Step-by-step explanation:
Given that,
X = 7x+5
Y = 9x-7
W = 112°
V = 90°
We need to find the measure of each angle. We know that the sum of angles of a quadrilateral is equal to 360°.
7x+5+9x-7+112+90 = 360
x = 10
So,
X = 7x+5 = 7(10)+5 = 75°
Y = 9x-7 = 9(10)-7 = 83°
