Answer:
a=35, b=14, c=5
Step-by-step explanation:
b+6=20, b+6-6=20-6, b=14
4c-6=14, 4c-6+6=14+6, 4c=20, 4c/4=20/4, c=5
a triangle's angles always add up to 180, 180-55-90(the square means right angle)=35
Answer:
(−1.5,1)
Step-by-step explanation:
Finding the distance, midpoint, slope, equation and the x y-intercepts of a line passing between the two points p1 (6,7) and p2 (-9,-5)
The distance (d) between two points (x1,y1) and (x2,y2) is given by the formula
d = √ ((X2-X1)2+(Y2-Y1)2)
d = √ (-9-6)2+(-5-7)2
d = √ ((-15)2+(-12)2)
d = √ (225+144)
d = √ 369
The distance between the points is 19.2093727122985
The midpoint of two points is given by the formula
Midpoint= ((X1+X2)/2,(Y1+Y2)/2)
Find the x value of the midpoint
Xm=(X1+X2)/2
Xm=(6+-9)/2=-1.5
Find the Y value of the midpoint
Ym=(Y1+Y2)/2
Ym=(7+-5)/2=1
The midpoint is: (-1.5,1)
Answer:
<2 = 129°
Step-by-step explanation:
if I || m then 5x+12 =m<2 and m<2 + 2x + 14 = 180°
2x + 14 + 5x + 12 = 7x + 26 =180°
7x = 154 ➡x = 21°
m <2 = 5×21 + 14
Answer:
sin^2α
Step-by-step explanation:
I will just pose x instead of alpha here to make things simpler
we know that sin^2x = 1 - cos^2x so...
we can rewrite using trigonometric identities (tan = sin/cos)...
Answer:
y=9x+5
Step-by-step explanation:
y=mx+b is the slope-intercept form where m is the slope and b is the y-intercept.
Given that m (the slope) = 9 and b (the y-intercept) = 5, we can substitute directly into the equation and get this answer:
y=9x+5
