Answer:
y = - 4
Step-by-step explanation:
Given
y = 2x + ( - 2) , that is
y = 2x - 2 ← substitute x = - 1
y = 2(- 1) - 2 = - 2 - 2 = - 4
This is confirmed by the point (- 1, - 4 ) on the graph
We can find this using the formula for arc length (where
is the radius of the circle and
is the central angle in radians):
![\textrm{Arc Length} = r\theta](https://tex.z-dn.net/?f=%20%5Ctextrm%7BArc%20Length%7D%20%3D%20r%5Ctheta%20)
In our problem, we are given
. This means that:
![\theta = \dfrac{12}{8} = \boxed{\frac{3}{2}}](https://tex.z-dn.net/?f=%20%5Ctheta%20%3D%20%5Cdfrac%7B12%7D%7B8%7D%20%3D%20%5Cboxed%7B%5Cfrac%7B3%7D%7B2%7D%7D%20)
The measure of the angle is 1.5.
Answer:
19 m
Step-by-step explanation:
base=x
leg=3x-2
3x-2+3x-2+x=45
7x-4=45
7x=49
x=7
leg=3x+2=3(7)-2=19
