first of all 5=74-43=2-3=2=1093276x—x8x6–628%+35455+7662772-6567=4552433w7=27272728=2892—x+665165=75. So X=75
Answer:
v = 15
Step-by-step explanation:
Sum of the angles inside a triangle add up to 180
angle 1 = 31
angle 2 = 4v+44
angle 3 = 180 - 9v
since 9v is the supplement to the angle inside the triangle then
some angle + 9v has to equal 180
which we can solve for the that angle to be 180 - 9v
therefore
180- 9v + 31+ 4v+ 44 = 180
Simplify it down by combining like terms
255 -5v = 180
subtract 255 to both sides
-5v = -75
divide by -5
v = 15
Answer:
9.89 m
Step-by-step explanation:
AC is the hypotenuse (H)
x is the opposite (O)
O and H are in sine
sin=O/H
H=O/sin
H=7.9/sin(53)
=9.89187169943418
3 SF
9.89 m
for problem 6, you will want to subtract both sides by 5.
n^2 + 7n + 10 = 0
then factor:
(n + 5) (n + 2) = 0
n+ 5 = 0, n +2 = 0
n = -5, n = -2
----------------------------
for problem 7, add - 12 and - 6 together
n^2 + 3n - 18
<em>(you can put </em>= 0 <em>next to the equation since that can make it easier to solve, I guess)</em>
n^2 + 3n - 18 = 0
then factor:
(n + 6) (n - 3) = 0
n + 6 = 0, n - 3 = 0
n = -6, n = 3
