Answer:
???????
Step-by-step explanation:
triangles add to 180 degrees
lets call the unknown angle y
82 + x + y = 180
we also know that y + (2x-20 ) = 180 because it is a straight line
lets solve this for y
y + (2x-20 ) = 180
subtract (2x-20) from each side
y = 180 - (2x-20)
y = 180 - 2x + 20
y = 200 -2x
substitute this in the triangle equation
82 + x + y = 180
82 + x + 200 -2x = 180
combine like terms
282 -x = 180
subtract 282 from each side
-x = -102
multiply by -1 on each side
x = 102
the exterior angle is 2x-20
exterior angle is 2(102) -20
exterior angle is 204-20
exterior angle is 184
This is impossible.
There is a mistake with this problem
The triangle is not a triangle. Angle y would be negative. y=-4
Answer:
(-2,0)
Step-by-step explanation:
To find the x intercept, set y =0 and solve for x
9x+3y = -18
9x +0 = -18
9x/9 = -18/9
x = -2
(-2,0)
The answer is 60 degrees angle
A: 112
b: 3 seconds
c: f(3) = 256
d: 7 seconds
Answer:
p > 63
Step-by-step explanation:
p/7-(9)>0
p
Simplify —
7
p
— - 9 > 0
7
p - 63
—————— > 0
7
Multiply both sides by 7
Add 63 to both sides
p > 63
