<h2>7x + 19 = 208</h2><h2>11x - 89 = 208</h2><h2>--------------------------------------</h2>
<u>Step-by-step explanation:</u>
let third angle be x
60° + 60° + x = 180° (Δ sum property)
x = 60°
so, this is a equilateral triangle (all Δ equal)
<h2>-----------------------------------------</h2>
in equilateral triangle --> all sides are equal
so, therefore =>>
7x + 19 = 11x - 89
19 + 89 = 11x - 7x
108 = 4x
108 ÷ 4 = x
27 = x
<h3>x = 27</h3><h2>-----------------------------------------</h2>
so variable
1.) 7x + 19
= 7(27) + 19
= 189 + 19
= 208
2.) 11x - 89
= 11(27) - 89
= 297 - 89
= 208
Answer:
measure of both angle is 66
Step-by-step explanation:
vertical angles are equal so,
6x+15=4x+32
6x-4x=32-15
2x= 17
X=8.5
now,
4X+32
= 4×8.5 +32
= 66
Answer:
the probability is equal to 0.0123
Step-by-step explanation:
given,
Probability of hitting a Target by A (p)= 1/3
Probability of not hitting a Target by A (q) = 1 - 1/3
= 2/3
given, problem follows negative binomial distribution
let X be the probability of hitting the target for first time in third throw
X follow NBin. (k = 3 , p = 1/3)
=
=
= 0.0123
hence, the probability is equal to 0.0123
18 gallons. If you multiply 25 by 18 you will get 450.
