Angles in a triangle- 180°
64+32= 98°
180-98= 82°
Part over whole ( whole is your % )
7/1OO% = 4/x
cross multiply & you get 7x/7 = 4OO/7
answer is x = 57.14%

Step-by-step explanation:
Answer:
a) 0.8
b)0.05
c)0.15
d)0.2
e)0.85
Step-by-step explanation:
a)
The probability of selecting student can be computed as
P(S)=number of students in survey/total number of individuals
P(S)=800/1000=0.8
b)
The probability of selecting faculty member can be computed as
P(F)=number of faculty member in survey/total number of individuals
P(F)=50/1000=0.05
c)
The probability of selecting administrator can be computed as
P(A)=number of administrator in survey/total number of individuals
P(A)=150/1000=0.15
d)
The probability of selecting faculty member or administrator can be computed as
P(A or F)=P(A)+P(F)-P(A∩F) as A and F are mutually exclusive so P(A∩F) will be zero,
P(A or F)=P(A)+P(F)=0.15+0.05=0.2
e)
The probability of selecting except administrator can be computed as
P(A')=1-P(A)=1-0.15=0.85
Angle QRT is an exterior angle to the triangle. The rule is that the exterior angle of a triangle is equal to the sum of its remote interior angles. Those remote interior angles are angle RTS and angle TSR. So our equation is
. We can remove the parenthesis and simplify by combining like terms to get 9x = 5x + 9 + x and 9x = 6x + 9 and 3x = 9. That means that x = 3.
